Response interceptor is not called on error about ng-http-interceptor

[gund]

What I meant by catch operator is not language try/catch construct but RxJs Observable .catch operator (like .do)

httpInterceptor.response().addInterceptor(res => {
      return res
        .do(r => doSideEffectsOnSuccess(r))
        .catch(e => handleErrorAndReturnNewObservable(e));
    });

For further details about catch operator usage please refer to RxJs catch documentation.

You can also use the second parameter of do():

httpInterceptor.response().addInterceptor(res => {
    return res.do(
      r => {
        console.log("Status: ", r.status);
      }, 
      err => {
        console.log("Error");
      }
    );
});

The first parameter can be replaced with null:

httpInterceptor.response().addInterceptor(res => {
    return res.do(
      null, 
      err => {
        console.log("Error");
      }
    );
});

In your code snippet I cannot see catch operator, maybe that is why you are missing errors?

I have the same error:

httpInterceptor.response().addInterceptor((res, method) => {
      try {
        return res.do(r => {
          try {
            console.log(method, r)
          }
          catch(ex){
            console.log("catcth 2", ex);
          }
          
        });
      }
      catch(ex) {
        console.log("error catch 1", ex);
      }
    });

only on success response is working
