Error on the TargetGroup when creating a lambda for the nodejs-graphql example

[HassenIO]

Describe your environment

I'm getting issue running the waypoint-examples/aws/lambda/nodejs-graphql example as is (with no change to the provided scripts).

• OS: MacOSX Ventura 13.4.1 darwin/arm64 (M1)
• Waypoint version:
  • CLI: v0.11.3 (2933d41)
  • Server: v0.11.3
• Docker version: 24.0.5

Describe the bug

Running waypoint up produces an error on the TargetGroup for Lambda:

 ! Creating TargetGroup for Lambda version
! ValidationError: Target group name 'waypoint-apollo-lambda-function-' cannot
  begin or end with '-'
  	status code: 400, request id: 8a3f2f36-eb22-43af-bca8-6fdc3418b666

Steps to Reproduce

As described in the tutorials, I ran the initialization commands as follow:

waypoint install -platform=docker -accept-tos
waypoint init

which both went successful.

The waypoint.hcl file is the same as in the example https://github.com/hashicorp/waypoint-examples/blob/main/aws/lambda/nodejs-graphql/waypoint.hcl

However, running waypoint up produces the following outputs:

waypoint up

Expected behavior

It should successfully deploy the NodeJS + Graphql application.

Additional context

None.

Is this not related to the TargetGroup requirement for the name to be less than 32 characters?

I found the following comment in the source code:

https://github.com/hashicorp/waypoint/blob/88abbbc33039d3ba82a49c5c759460c999c8370e/builtin/aws/lambda/platform.go#L549

Also, the string waypoint-apollo-lambda-function- is 32 characters long, proving the issue comes from that.

A solution is to update the code example to a shorter app name. Also, I'm unsure if there is an option to set a custom TargetGroup name in the waypoint.hcl file (I'm just starting to learn it).
