Pipeline config not showing up on synth output

Reproduction Steps

const lambdaWithStash = `
#set($ctx.stash.newId = $util.autoId())
{"version": "2017-02-28", "operation": "Invoke", "payload": $util.toJson($ctx)}
`
const passThrough = `$util.toJson($ctx.result)`

export const resolverDefaults = {
  requestMappingTemplate: Appsync.MappingTemplate.fromString(lambdaWithStash),
  responseMappingTemplate: Appsync.MappingTemplate.fromString(passThrough),
}

// this == CDK.Stack
new Appsync.Resolver(this, 'pipeline', {
      ...resolverDefaults,
      api: Graphql, // Appsync.GraphQLApi
      typeName: 'Conversation',
      fieldName: 'messages',
      pipelineConfig: {
        functions: ['lambda1', 'lambda2'] // valid lambdas on my Lambda console
      }
    })

I’m passing a valid, as per cdk types, pipelineConfig but it shows as undefined in my cdk synth output, causing deploy to fail even though my cdk code looks correct

Okay I think I found the root of the confusion.

The Function that can be added to the pipelineConfig is not a Lambda Function. Instead, it is AppSync::Function.

See documentation on pipelineConfig here.

See documentation on functionConfiguration here.

See documentation on appsync:CreateFunction here.

If you want to use Lambda Functions, I suggest using the addLambdaDataSource and createResolver method outlined above.

That being said, CDK doesn’t have implementation for AppSync Function so I will close this issue and opening #9092 for a feature request for AppSync function creation.
