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

However, I get the following error on making a call to DestinationAccessor.getDestination(name);

Hi @anupriyaSap,

Could you please attach full stack trace and DEBUG logs from your application? We need DEBUG logs enabled for packages com.sap.cloud.sdk and org.apache.http.wire. Refer here for more details.

Please remove any sensitive information from the wire logs before sharing them.

Regards, Kavitha

Hi @anupriyaSap,

From the stack trace shared over email, I see the following root cause:

STDERR Caused by: java.lang.NoClassDefFoundError: javax/cache/configuration/Configuration

Please check your project's dependency tree and see if an older version of javax.cache:cache-api gets included. Inside the SDK, we use javax.cache:cache-api:1.1.1. You could also use our BOM in your dependency management section to minimise dependency conflicts.

Also, since you mentioned you updated to version 5 recently and use DwC, please also check if you did all the steps listed here during migration.

Regards, Kavitha
