Internal Server Error when create_item

I am trying to create a item using the following query (with postman):

However I get Internal Server Error (500) .
What is the problem with these queries?

Hi @Oscare, welcome to the community!

I believe you’re running into this error because your column_values variable need to be in JSON formatting, like so:

{ "column_values" : "{\"texte\":\"3\"}" }

Let me know if this helps!
