Konfiguracja debuggera vscode w zdockeryzowanym projekcie django nie działa.

Za każdym razem kiedy uruchamiam debuggera dzieją się różne rzeczy, ale niekoniecznie takie, jakich oczekuję.
Zacznijmy od początku:

Uruchamiam projekt docker-compose up
Wchodzę na adres z localhosta, żeby sprawdzić czy cokolwiek działa - próba zalogowania - nie działa, backend leży.
Co zabawne kontener stoi bo mam włączone remote containers w vscode.
Pierwsza próba uruchomienia debuggera - zwrotka z debug console

Attached!
System check identified some issues:

WARNINGS:
workflow.State.additional_values: (fields.W904) django.contrib.postgres.fields.JSONField is deprecated. Support for it (except in historical migrations) will be removed in Django 4.0.
	HINT: Use django.db.models.JSONField instead.
Operations to perform:
  Apply all migrations: accounts, auth, contenttypes, files, mambu, otp_totp, sessions, token_blacklist, workflow, zoho
Running migrations:
  No migrations to apply.

i się wyłączyło. backend dalej leży.

Druga próba włączenia debuggera:

Attached!
System check identified some issues:

workflow.State.additional_values: (fields.W904) django.contrib.postgres.fields.JSONField is deprecated. Support for it (except in historical migrations) will be removed in Django 4.0.
	HINT: Use django.db.models.JSONField instead.
Zoho Configuration failed, check that you have all variables ZOHO_TOKEN_URL, ZOHO_REST_API_KEY, ZOHO_CURRENT_USER_EMAIL

i wyłączyło. backend wstał, da się zalogować na stronę i robić różne cyrki.

Trzecia próba włączenia debuggera kończy się okienkiem z napisem connect ECONNREFUSED 127.0.0.1:5678.

Jakieś tipy?
