Cannot get Quickstart App tutorial to work

sdbbs · March 15, 2023, 8:55am

I have found Quickstart guide - tried following it, cannot get it to work.

Then I found Creating new Item View which referred to a “Quickstart board view github page” https://github.com/mondaycom/welcome-apps/tree/master/apps/quickstart-react - which I tried following as well, and I cannot get it to work either.

I really hate documentation not working and having to waste time on writing posts like this, but I’ll lay out my steps here - and hopefully someone will tell me what is wrong.

I’m trying this on Ubuntu 20.04, I have installed node via:

curl -fsSL https://deb.nodesource.com/setup_19.x | sudo -E bash -
sudo apt install nodejs

First I clone the welcome-apps repo:

git clone https://github.com/mondaycom/welcome-apps.git mondaycom_welcome-apps_git
cd mondaycom_welcome-apps_git/
cd apps/quickstart-react

And then I follow https://github.com/mondaycom/welcome-apps/tree/master/apps/quickstart-react :

Run the project

In the project directory, you should run:
npm install
And then to run an application with the monday tunnel, run:
npm start
Find the provided URL in your terminal. This is your public URL, and you can use it to test your application.
Example: https://unsightly-chickaree-35.tunnel.monday.app

Ok, I’m the project directory already, so:

$ npm install

Hello Monday Apps!

Hello, your user_id is: still loading. Let’s start building your amazing app, which will change the world!

So, I guess, something here works.

Let’s go further along the README in https://github.com/mondaycom/welcome-apps/tree/master/apps/quickstart-react :

Configure Monday App

Open monday.com, login to your account and go to a “Developers” section.

Create a new “QuickStart View Example App”

I guess they should have wrote “click Create App” first:

Then, in the next screen, I can set the name to “QuickStart View Example App”:

… and click on “Save App”

Open “OAuth & Permissions” section and add “boards:read” scope

Well, it’s not called “OAuth & Permissions” anymore, apparently - and they forgot to say “Save Feature” again, but OK - what are online apps for, but to make life harder?

Open “Features” section and create a new “Boards View” feature

More accurately - click the “+” by the Features section:

… and on the following New Features screen, select the “Board Views” Feature Type:

… and click “Let’s Go”.

However, what they also forgot here, is that there is there are more steps here - next is choosing the template; I guess “Quickstart - ReactJS” is the right one?

Make the selection, click Next, and you get to the final screen “Set up your dev environment”:

Here I’m told to run npx ... command, but I’ve already started a local server with npm ... previously, so at first I tried ignoring this page, and closing the “wizard” via the upper right x. However, this results with the Feature not being created - and thus no “view setup” tab as in the next step of the tutorial; so:

As one can see from the npm logs above, the URL I got here was https://plump-antelope-27.tunnel.monday.app; so I’m trying to enter that as “Paste the URL from the previous step”:

… and I click on “Go To Editor” here.

Open “View setup” tab and fulfill in “Custom URL” field your monday tunnel public URL, which you got previously (example: https://unsightly-chickaree-35.tunnel.monday.app)

Well, entering the URL is now done in the previous step, - but the “View Setup” opens next automatically anyways:

… so we can confirm we have the right URL address.

Click “Boards” button and choose one of the boards with some data in it.

Ok:

… and click “Save” at end of it.

Click “Preview button”

I click “Go to preview” button next, and I get a blank screen first:

… and after a few minutes wait, I get:

… an error, " 504 Gateway Time-out — nginx/1.23.1".

This is most definitely not the rendering I expected.

Enjoy the Quickstart View Example app!

Eh, … I wish

So, why can’t I get the Quickstart tutorial to work?

Hello there @sdbbs,

Thank you for that detailed step-by-step!

You said you could see the screen that says “Hello Monday Apps!” in your screen when you went to http://localhost:8301.

What happens if you go to the URL that the monday tunnel gives you (https://plump-antelope-27.tunnel.monday.app)?

If you see it in your localhost but it does not work on the URL given by the monday tunnel, I would advise you to check your environment to see if you may have something like a firewall or some antivirus software preventing your project from being exposed to the internet via monday tunnel. I have seen issues like this one a few times and they were resolved by checking and setting the environment so that it does not block monday tunnel.

Please let me know if that is the case!

Looking forward to hearing from you!

Cheers,
Matias

Many thanks for the response, @Matias.Monday :

Yes

Thankfully, I’ve still had the same server running, and: I got the same error message when I open that URL in my browser: 504 Gateway Time-out ; nginx/1.23.1

I don’t have firewalls on my Ubuntu, so I’d guess it is some NAT issue between routers …

But that is what surprises me a bit with tunnels: in the past I’ve had immense problems with NAT and access to machines, until I figured out how to use SSH reverse proxy, and in that case, since I run ssh on client machine and I initiate connection, I usually do not get blocked by NAT. (and of course, I run reverse ssh on the same Ubuntu machine where I’ve ran the procedure described in OP without a problem)

Since here with npm I also initiate a connection to remote server with the purpose for establishing a tunnel, I am kind of surprised that router ports and NAT would have an influence - but I’ll check my environment.

Are there any IP ports specifically that need to be open?

Matias.Monday · March 15, 2023, 10:10am

Hello again @sdbbs,

I will check with the team responsible for the monday tunnel to see if they can give you some guidance here. I will update you when I get a reply about it!

Thanks @Matias.Monday - here is a bit more info: gave the old Wireshark a spin; and once I start the server (but before any URL calls in browser), I can see this:

That is, my local nodejs server does indeed talk to tunnel.monday.app - and gets a response that mentions Let’s Encrypt and Internet Security Research group etc; however this is a HTTPS connection, so the conversation is encrypted.

However, since I can see both my local nodejs server talking, and tunnel.monday.app app responding (even multiple times toward the end - note red and blue below):

… that means only one thing: this is not an issue with port blocking/NAT - as there is communication between the ports (in fact, just the signature “nginx” in the 504 message means we did get something back from tunnel server).

Which also means, now the problem is even more complicated to troubleshoot

One thing I can notice in the Wireshark log, are very many packets marked with “[TCP Analysis Flags]: [Expert Info (Note/Sequence): ACK to a TCP keep-alive segment]”, that is, Wireshark captured a packet, which Wireshart thinks is an ACK to a “keep-alive” packet (where, apparently, those “keep-alive” packets do not require ACKs). This might be an issue with the nodejs server …

EDIT: forgot to mention - I restarted the nodejs server a couple of times, getting new URLs in the process; and at a certain point, for an unknown reason, instead of the browser blocking for a few minutes and then returning 504 Gateway Time Out, it returned a 404 (with just 404 written as plain text) almost instantly; not sure how to interpret this … other than that there was some connection established between my local nodejs server, and the remote tunnel server.

Hello again @sdbbs,

I spoke with the team in charge of the monday tunnel.

They will take a look into this to try to avoid devs from having to check their environments as much as possible.

But regarding your particular case, I am afraid I don’t know where in your environment the issue might be.

Maybe someone in the community has been trough the same one and can help

Thanks @Matias.Monday :

Good to know and have it stated explicitly, thanks! I’ll try and see what I can do on my end …

But I thought of one thing: since it is confirmed that IP ports are not blocked, and there is conversation between my local nodejs server, and tunnel.monday.app - could this be a permissions issue? Maybe I need to be registered as a developer somewhere, or maybe I need admin privileges somewhere?

Probably not. This is an issue that affects some users and many of them are able to work around it, but we are aware of some architecture and hosting changes we will need to work on with the tunnel.

We are aiming on making this changes in the next two months.

In the meantime, you could use something like ngrok for testing.

We will post in our changelog when the changes to the monday tunnel are implemented.
