I am attempting to expand the tutorial to include a /notes2-api as part of the project. I can’t seem to edit the notes2 serverless.yml to create it. I can create it as a separate url. but can’t figure out how to create it so there is a structure:

/billing
/notes
/notes2

I use parts of the billing-api yml such as the api imports

apiGateway:
restApiId:
‘Fn::ImportValue’: {self:custom.stage}-ExtApiGatewayRestApiId restApiRootResourceId: 'Fn::ImportValue': {self:custom.stage}-ExtApiGatewayRestApiRootResourceId

but it still fails with:
The CloudFormation template is invalid: Template format error: Unresolved resource dependencies [ApiGatewayRestApi] in the Resources block of the template.

I obviously have something wrong that causes the error in the cloudformation template, but I don’t see many moving parts and which ones need some change to get the correct values.

I think we talked about this. But we needed to remove the included files in the resources section.
