TokenRequestFailedException when trying to access destinations with OAuth2ClientCredentials type Authentication

[anupriyaSap]

Issue Description

We are trying to connect to say a microserviceB from microserviceA. The destination is configured with OAuth2ClientCredentials authentication. We have a certificate which we have added in the destination and a clientId. We have url to call B and a token service url.

Expectation is that the microserviceA sdk library will make a connection to the destination with DestinationAccessor.getDestination(name) and internally generate the token with the tokenUrl and call the url to microserviceB.

But when the code - DestinationAccessor.getDestination(name); is called, I get the following exception.

com.sap.cloud.sdk.cloudplatform.thread.exception.ThreadContextExecutionException: com.sap.cloud.sdk.cloudplatform.resilience.ResilienceRuntimeException: com.sap.cloud.sdk.cloudplatform.thread.exception.ThreadContextExecutionException: com.sap.cloud.sdk.cloudplatform.security.exception.TokenRequestFailedException: Failed to resolve access token.

I can generate a token via client and call the microserviceB via a client.

Impact / Priority

Its a P1 - top priority for us as our code freeze for go live is on 22 August.

Affected development phase: Development closure soon

Impact: Blocked

Timeline: e.g. Go-Live is in 4 weeks
