Description

Bug:
After I rename a custom javascript resolver, the build fails in Amplify Gen 2 console however the build & deployment are successful in local cloud sandbox environment.

Steps to reproduce:

1. Create an additional AppSync API (as we have exceeded 1MB size limit of Amplify data stack a long time ago)
2. Add an external DynamoDB database in backend.ts file and create a datasource for the AppSync API
3. Add a mutation in graphql schema file
4. Create a custom javascript resolver function and add it to backend.ts file
5. Deploy the changes
6. Now rename the resolver function
7. Deploy again

This time the build fails in Amplify Gen 2 console.

getIncidentAndStakeholder.js is the updated resolver file name and it is available in the code repository.
