Your problem
I use the integration bundle to integrate the 3rd party service with Mautic.
Using the three legged OAuth2 to authorize I get the 500er.
These errors are showing in the log:

Steps I have tried to fix the problem:
Modify the IntegrationsBundle/Auth/Support/Oauth2/Token/TokenPersistence.php. Replace IntegrationToken to RawToken. Works properly after that.
