Jest mockRejectedValue throws unhandled promise rejection in node

I'm trying to write a test in jest but keep getting UnhandledPromiseRejectionWarning when I try to use mockRejectedValue

The code looks like this:

it('Should set error message when call fails', async () => {
        const context = mockActionsContext();
        const user = {
            username: 'alice',
            password: 'password'
        };

        const getError = new Error('network error');

        (AuthService.login as jest.Mock) = jest.fn().mockRejectedValue(getError);
        await actions[ActionTypes.USER_LOGIN](context, user);

        // Check is the commits are called
        expect((context.commit as any).mock.calls).toEqual([
            [MutationTypes.USER_LOGIN],
            [MutationTypes.USER_LOGIN_ERROR, 'Oops, something went wrong. Try again later!']
        ]);

        // Login service is called with user login
        expect(AuthService.login as jest.Mock).toHaveBeenCalledWith(user);
    });

The AuthService.login returns an axios.post which I try to overwrite with a mock. actions[ActionTypes.USER_LOGIN](context, user) calls the Authservice.login

The test is passing but I don't want any unhandled promise rejection. Anybody an idea how to fix it?

Edit @goodmorningasif thanks for your reply. I've been looking at it too long I thing :)

The action looks as following:

    [ActionTypes.USER_LOGIN]: ({ commit }: Context, payload: User) => {
        return new Promise((resolve, reject) => {
            commit(MutationTypes.USER_LOGIN);

            AuthService.login(payload)
                .then((token) => {
                    commit(MutationTypes.USER_LOGIN_SUCCESS, token);

                    localStorage.setItem('user-token', token);
                    client.defaults.headers.common.Authorization = `Bearer ${token}`;
                    resolve(token);
                })
                .catch((error) => {
                    let errorMessage = 'Oops, something went wrong. Try again later!';

                    if (error?.response?.status === 401) {
                        errorMessage = 'Unknown username and password combination!';
                    }

                    localStorage.removeItem('user-token');

                    commit(MutationTypes.USER_LOGIN_ERROR, errorMessage);
                    reject(error);
                });
        });
    },

SOLUTION

In my case the action is returning a promise witch would get rejected. In the test, I'm calling the action directly and not catching the rejection.

await actions[ActionTypes.USER_LOGIN](context, user).catch(() => null);

This fixed it.
