Describe the bug
I am following the documentation for Calling GraphQL API from a Lambda function and everything works when deployed but I cannot mock it locally. First issue was that amplify mock does not support ES modules and therefore the examples in the documentation are not working with it. I fixed that by using node-fetch v2 which works with commonjs and switched to requiring modules so mocking would work.
Next issue is that the example code provided for mutation works when deployed in aws but does not work with amplify mock api and amplify mock function. The error returned by graphql local endpoint is "Must provide Source. Received: undefined".
Expected behavior
The examples provided in the documentation should work as expected when mocking locally and data should be inserted in the local graphql.
Reproduction steps
- Create function for graphql mutation following the example here)
- Modify code to use commonjs modules instead of ES ones so amplify mock function would work
- Execute amplify mock function with sample event
