3750496 - Error: "[BW API] Failed to fetch the CSRF token required to start the BW process chain"

 DataSphere Task Chains have started to fail when calling BW Bridge Process Chains. The error messages as below:

[BW API] Failed to fetch the CSRF token required to start the BW process chain. Status Code: 401, Status Message: Unauthorized

SAP Datasphere

SAP increased caching times for the JWT token used to fetch a CSRF token for the BW Bridge use case. And your Max ID. Token age config yields an upper bound for the token age, which now causes issues.

The default token time for JWT tokens we use is 12hours so a Max ID Token age of 12hours (720mins) would be the "safest" choice to make your tasks execute successfully again.
