graphql / Apollo test case for a service call fails with Error: Expected one matching operation for criteria "Match DocumentNode", found none

Question

I am trying to write a test for an angular component service call which is using graphql & Apollo and I end up getting this Error.'Error: Expected one matching operation for criteria "Match DocumentNode", found none.'.

I have also tried putting '__typename' in each returned response but nothing worked to fix the issue.

component.spec.ts

  it('should call getCDMADetails()',()=>{
      const tnNumber = '8934216345';
      const userQueryDetails = gql `
      query
      {
        cdmaLineFeatures (telephoneNumber: "8934216345"){
          sMSFeatures {
            smsProvisionedReceive,
            smsProvisionedSend
          }
        }
      }
      `;
      const TEST_Login = {
        'data': {
          'cdmaLineFeatures': {
            'sMSFeatures': {
              'smsProvisionedReceive': "YES",
              'smsProvisionedSend': "YES",
              '__typename': "DefinedOnBackend"
            }
          }
        }
      };
      homePageService.getCDMADetailsServiceInfo(tnNumber);
      component.getCDMADetails();
      controller.expectOne(addTypenameToDocument(userQueryDetails)).flush(TEST_Login);
      expect(component.getCDMADetails).toBeTruthy();
      controller.verify();
    });
