I have an integration with Paypal that always fails after it retrieves a new Access_token after the previous token expired. It fails with the following error message:
{"error":"invalid_token","error_description":"Access Token not found in cache"}
After a restart of the web application, the same code to fetch an Access_token works.
The only differences between the two responses from "/v1/oauth2/token" is that access_token and nonce are different (as expected).
I have verified that the updated token is used in the call that fails.
Any ideas why it works to fetch a new access token after a restart, but not when the previous access token has expired?
I have seen a few other questions with this error message, but none of them have a solution to the problem.
