Mock function not using mock API

Note: If your issue/bug is regarding the AWS Amplify Console service, please log it in the Amplify Console GitHub Issue Tracker

Describe the bug When testing my lambda function via mock, the API_MYPROJECT_GRAPHQLAPIENDPOINTOUTPUT environment variable points to amazonaws.com even though the mock api server is running.

Amplify CLI Version 4.41.1

To Reproduce Terminal 1: amplify mock Terminal 2: amplify status Terminal 3: amplify mock function mylambda --event src/event.json --timeout 7

Expected behavior amplify status should show the AppSync mock endpoint that’s running. The API_MYPROJECT_GRAPHQLAPIENDPOINTOUTPUT environment variable should point to the mock endpoint.

Desktop (please complete the following information):

• OS: Mac BigSur 11.1 Macbook Pro M1
• Node Version v14.12.0

Additional context The react app DOES correctly switch between the cloud and the mock endpoint. GraphiQL explorer runs on localhost.

Thanks

@m2broth Yes, my workaround it to overwrite the APIKEYOUTPUT variable when mock is running.

In index.js I add the following:

exports.handler = async (event) => {
    //console.log('process.env', process.env)
    //console.log('event', JSON.stringify(event))
    if (process.env.AWS_EXECUTION_ENV === 'AWS_Lambda_amplify-mock') {
        console.log("BUGFIX: overwrite GRAPHQLAPIKEYOUTPUT to use mock key")
        process.env.API_AMPYMAIL_GRAPHQLAPIKEYOUTPUT = 'da2-fakeApiId123456'
    }

Hope that helps.

(PS: If you’re also using a mock GraphQL, beware it behaves differently than production for queries that return non-nullable results: https://github.com/aws-amplify/amplify-cli/issues/6450)

@attilah Exactly correct.

I’d like to do all my testing locally. The webapp (react) is using the mocked graphql and S3. I have an amplify generated lambda function (a webhook that will be called by a 3rd party). When I mock test the function, it always writes data to the cloud instead of the local gql server.

I have 3 terminals, one in Visual Studio running the webapp, one running “amplify mock” for api & storage, and one to mock trigger the lambda function.

Thank you, I’m enjoying using Amplify very much.
