Cannot parse certificates in test method

[swimmingdale]

Describe the bug

After properly implementing "endpoint_urls" functionality the certificate being passed to "test" cannot be parsed by the integration-sdk-adapter-library with version 1.0.2.

Reproduction steps

1.Implement "endpoint_urls" to return an https url of a valid https endpoint
2.test with mp-test by choosing Test Connection
3.When the test framework passes the certificate it cannot be parsed by the integration-sdk-adapter-library. The error is:
Expected JsonPrimitive at 0, found {"cert_pem_string":"-----BEGIN CERTIFICATE-----\n....

Expected behavior

The library should parse the given certificates correctly
