The JWT Token got generated with a different JWT Library as Pega is using.

When we realized that pega is using the com.nimbusds library, we changed the generation of the token by using the nimbusds library from the following maven dependency and it worked.

<dependency>

                  <groupId>com.nimbusds</groupId>

                  <artifactId>nimbus-jose-jwt</artifactId>

                  <version>6.0.1</version>

            </dependency>
