My app panel - 400 on pipedrive

My app is giving us a connect problem to our rest, when we use the update button in our app panel that connect to our rest, we have these console error on pipedrive:

vendors.917fad4cf03851fd8ed7.js:29 GET **400**

We test these in postman and works good, but not in our app panel from pipedrive.
Any suggestion? to fix these.

Hey Pablo,

Sorry for the delayed response.

Can you tell if you’re still encountering this issue? If so, could you DM me your Company_ID?
