Subject: Help Needed with JWT Decoding Issue for a Specific User

Hi everyone,

I have an app on Monday Marketplace called Lead & Contact Info Finder. Everything works as expected for our users except for one specific case.

Issue:
I’m encountering a problem when trying to decode a JWT token for a particular user. The error I’m getting is:

makefile

Copy code

jwt.exceptions.InvalidSignatureError: Signature verification failed

Technical Information:
In my Python code, I use the following snippet to decode the token:

python

decoded_data = jwt.decode(
    authorization,
    monday_sign_secret,
    algorithms=['HS256'],
    options={'verify_aud': False}
)

Here:

  • authorization is the JWT token received in the event.
  • monday_sign_secret is my signing secret.

This code works perfectly for all other users, but I can’t decode the token for this specific user using the same secret.

Question:
Has anyone encountered a similar issue, or does anyone have insights into what might be causing this JWT signature verification to fail only for this user?

Thanks in advance for any help or suggestions!

Best,
Doron

Hello there @doronafota and welcome to the community!

I hope you like it here :muscle:

It sounds odd that this is happening for only one specific user.

Would you be able to please fill this form adding as much information as possible to it (such as account ID, board IDs, item IDs, timestamps, etc.) so that our team can take a look into it?
