Cannot find function config for function : undefined

[eerenwong]

Did anyone know how to solve this issue?

My project DynamoDB is start separately serverless dynamodb start --stage dev

Appsync emulator command: yarn appsync-emulator --port 62222

Mutation:

mutation createData{
    createData(
        name:"John"
        gender: 0
        mobile: "123456789"
    ) {
        id
    }
}

Mapping Template VTL:

  #set( $data = $context )
  #set( $data.arguments.id = "$util.autoId()" )
  #set( $data.arguments.user_id = "\${context.identity.name}" )
  #set( $data.arguments.created_by = "\${context.identity.name}" )
  {
    "version" : "2017-02-28",
    "operation": "Invoke",
    "payload": {
      "resolve": "CREATE.DATA",
      "context": $util.toJson($data)
    }
  }

When I run test and came out this:

✖ error Mutation.createData failed
✖ error Error: Cannot find function config for function : undefined

@eerenwong -- looks like your serverless config thinks this mutation has a lambda data source.

Check out the example config which shows you how to create a mutation with a dynamo data source
