Application callback URLs encoding problem

When I deploy the following application

clients:
  - name: 'MyApp'
    app_type: 'spa'
    oidc_conformant: true
    is_first_party: true
    callbacks:
      - '##MYAPP_CALLBACK_URLS##'
    jwt_configuration:
      alg: 'RS256'
      lifetime_in_seconds: 36000
      secret_encoded: false
    grant_types:
      - authorization_code
      - implicit
      - refresh_token

with MYAPP_CALLBACK_URLS set to

MYAPP_CALLBACK_URLS=http://localhost:3000/authenticated, http://localhost:3080/authenticated

Auth0 complains that callback URL is not listed in the app. When I open the app settings and manually delete and re-add the spaces everything works. Visually there’s no difference but certainly the spaces are not what they appear to be.

callbacks:
 - '##CALLBACK_URL_1##'
 - '##CALLBACK_URL_2##'

are working fine.

callbacks: @@MYAPP_CALLBACK_URLS@@

working fine if MYAPP_CALLBACK_URLS is defined as array in the config:

"AUTH0_KEYWORD_REPLACE_MAPPINGS": {
    "MYAPP_CALLBACK_URLS": ["https://example.com/login", "http://localhost/login"]
  }

and

callbacks: ##MYAPP_CALLBACK_URLS##

working fine if MYAPP_CALLBACK_URLS is defined as stringified array in the config:

"AUTH0_KEYWORD_REPLACE_MAPPINGS": {
    "MYAPP_CALLBACK_URLS": "[\"https://example.com/login\", \"http://localhost/login\"]"
  }

I will close the issue for now. I will try doing what is suggested by @zxan1285 and come back if needed.
