Error message

Inactive user

What it means

Default-parameter twin of error 55: `get_current_active_user` (`Security(get_current_user, scopes=['me'])`) raises HTTP 400 'Inactive user' when the resolved, scope-checked user has `disabled: True`. Sample user `alice` triggers it.

Solutions

1. Authenticate as an active user (`johndoe`).
2. Set the user's `disabled` field to `False`.
3. Show a disabled-account message; do not retry.

Example fix

# before
# me-scoped token for disabled 'alice' => 400
# after
# me-scoped token for active 'johndoe' => 200

None

def is_inactive(resp) -> bool:
    return getattr(resp, 'status_code', None) == 400 and resp.json().get('detail') == 'Inactive user'

try:
    me = client.get('/users/me/', headers=auth_header(token))
    me.raise_for_status()
except httpx.HTTPStatusError as e:
    if e.response.status_code == 400 and e.response.json().get('detail') == 'Inactive user':
        prompt_reactivation()
    raise

When it happens

Trigger: `GET /users/me/` with a valid `me`-scoped JWT whose user is disabled.

Common situations: Disabled account with valid outstanding scoped JWT; flag not reset on reactivation.
