Error message

run 不存在

What it means

HTTP 404 raised by POST /diet/runs/{run_id}/replay when the target run does not exist. Replay re-executes the pipeline using the input persisted with the original run, so a missing row (or one without a dict 'input' column — that variant raises ValueError -> 400 in the service layer) cannot be replayed.

Solutions

1. Fetch a valid run id from GET /diet/users/{user_id}/runs or a fresh /diet/recommend response.
2. If replaying programmatically, check existence with GET /diet/runs/{run_id} first.
3. Note the distinct 400 case: a run that exists but lacks a dict input fails in replay_diet_run, not here.

Example fix

# before
requests.post(f'{base}/diet/runs/old-id/replay')  # 404

# after
runs = requests.get(f'{base}/diet/users/{uid}/runs').json()['items']
rid = runs[0]['diet_run_id']
requests.post(f'{base}/diet/runs/{rid}/replay')

row = requests.get(f"{base}/diet/runs/{rid}").json()
if not isinstance(row.get("input"), dict):
    raise ValueError("run has no persisted input; replay impossible")

try:
    new_run = requests.post(f"{base}/diet/runs/{rid}/replay").json()
except HTTPError as e:
    if e.response.status_code == 404:
        raise LookupError("original run missing; cannot replay")
    if e.response.status_code == 400:
        raise ValueError(e.response.json()["detail"])  # e.g. missing input
    raise

When it happens

Trigger: POST /diet/runs/<unknown-id>/replay with optional body; run id non-existent after strip, or storage reset lost the run.

Common situations: Replaying from stale UI state after backend restart; automated tests replaying hard-coded ids.
