PHP DocuSing: after updating to Laravel 9 getting the error non successful HTTP code [400] User not found for JWT

Question

I've integrated DocuSign API with my Laravel App few months back with JWT Authentication. It was working without any issues so far. Two days ago we updated our app to Laravel 9 and since then getting this error while using the DocuSign API:

Error while requesting server, received a non successful HTTP code [400] with response Body: O:8:"stdClass":2:{s:5:"error";s:13:"invalid_grant";s:17:"error_description";s:14:"user_not_found";}

I've checked the configuration for Integration Key, User GuiId. Everything is matched and we didn't change it. So wondering why we're getting this error? Is it related to Laravel upgrade? I googled but didn't see any specific issue which matches with our issues.

Anyone else getting the same after upgrading to Laravel to 9? Any assist from DocuSign team on this issue would be very helpful!

Answer 1

Doubt this error is directly connected to the Laravel upgrade. This error means that you provided the wrong userID (GUID) when requesting JWT.

Make sure:

The userID is from the same environment (Production vs. Development env). That means you need to check the URLs and make sure they match as well (Prod vs. Dev)

Make sure this GUID matches the account you are using.

Just in case, double check your RSA private key. You cannot see the value, so you may need to generate a new one.
