Error in unit test in service of my angular apollo application

Question

I am unit testing my angular apollo app. I always get the same error:

Error: Expected one matching operation for criteria "Match DocumentNode", found none.
            at ApolloTestingBackend.expectOne (node_modules/apollo-angular/fesm2020/ngApolloTesting.mjs:135:19)
            at UserContext.apply (src/app/my-service.service.spec.ts:66:35)

Chrome 103.0.5060.53 (Linux x86_64): Executed 1 of 1 (1 FAILED) (0.108 secs / 0.092 secs)

This error occurs on the line:

const op = apolloController.expectOne(QUERY_GQL);

I have already reviewed all the related posts and none of them solve the problem. Someone could help me?

I am waiting for a response from someone who can solve my problem. Thank you very much.

Greetings.
