Hi Team,
I'm reaching out regarding an issue with JWT Authentication. When we create a new app on the developer portal and generate new credentials for JWT, we encounter a 500 server error. Using our older JWT credentials works without issues.
When we send requests through Postman, we've observed that the server-side issue is related to the access token. The access token received from the server is incomplete; it seems to be truncated and ends with ellipses (...). Comparing this with the access token from the older credentials, which consists of four complete lines, the older token works fine for us. However, the new app does not provide the expected token.
Our client is also facing similar issues.
Could you please investigate and resolve this issue?
