Custom source paths not supported

[MartinRamm]

• Given I create a architect project with a custom HTTP source path as seen in https://arc.codes/docs/en/guides/developer-experience/custom-source-paths (e.g. whatever/http/dir/you/want),
• and I start the sandbox,
• when I call the endpoint with the custom source path, I get the following error response:

StatusCode: 502
Error:

Lambda handler not found

Could not find Lambda handler at: ${repositoryRoot}/.build/whatever/http/dir/you/want

Please create a handler file, or run [npx] arc init, or add the following to your project preferences (preferences.arc or prefs.arc) file and restart Sandbox:

@create
autocreate true

Note that this file exists and is a valid lambda handler: ${repositoryRoot}/whatever/http/dir/you/want/index.ts
