Solutions

  1. Verify the id by listing users or checking the creation response that returned it.
  2. Confirm you're pointed at the right database/environment.
  3. Trim/validate the id client-side before the call.
  4. If the user should exist, check the DB directly for the row and any deletion logic in db_manager.

Example fix

// before
const user = await api.get(`/users/${userId}`);
// after
if (!userId || userId === 'undefined') throw new Error('missing userId');
const user = await api.get(`/users/${encodeURIComponent(userId.trim())}`);
Defensive patterns

Strategy: validation

Validate before calling

assert user_id and user_id not in ('undefined','null','None')
resp = await client.get(f"/users/{user_id}")
if resp.status_code == 404: handle_missing_user()

Type guard

def is plausible_user_id(uid: str) -> bool:
    return isinstance(uid, str) and len(uid.strip()) > 0 and uid not in {"undefined", "null"}

Try / catch

try:
    user = await client.get(f"/users/{user_id}").json()
except NotFoundError:
    user = None  # first-run / deleted user; create if needed

Prevention

When it happens

Trigger: GET /users/{user_id} with an id not present in the database; user deleted; id copied with whitespace/case differences if the DB collation is case-sensitive.

Common situations: Client stores a stale user id after DB reset; frontend passes undefined producing 'None'/'undefined' string ids; environment mismatch (querying dev DB for a prod-created user).
