3352445 - "Unable to parse oauth token... statusCode: 401" error when connecting to an external system - Integration Center

You have created OAuth Configurations for external system in Security Center to be used in your Integration Center job.

When executing the Integration Center job it is failing & you see the below errors in the Event Logs:

• "Unable to parse oauth token response due to HTTP operation failed invoking https://example_oauth_token_url.com/token with statusCode: 401"
• "ServiceApplicationException: Failed due to - Failed to get access token due to Response from server https://example_oauth_token_url.com/token"

The same OAuth credentials are working without issue & successfully authenticate against the external system when tested in an external REST client (e.g. Google Postman).

This is a known limitation of the Microsoft package/code used in the OAuth implementation for Security Center where their token endpoint is unable to parse OAuth token when there are special characters being used in the client_secret

Please use a client_secret which does not contain special characters.
