observability-race-condition-deleting-a-score-within-20-seconds-of-creation-via-f7ff79d0

THEN To prevent the race condition, check existence of the score before deleting it. On the server side, modify the DELETE endpoint to return a 404 status when the score does not exist. On the client side, implement a retry mechanism that delays deletion until the score is confirmed created, or query the score before deleting.

import requests

# After POST, poll until score is retrievable
score_id = 'abc123'
for _ in range(5):
    resp = requests.get(f'{LANGFUSE_API_SCORES}/{score_id}', auth=(PUBLIC_KEY, SECRET_KEY))
    if resp.status_code == 200:
        break
    time.sleep(2)
# Then delete
requests.delete(f'{LANGFUSE_API_SCORES}/{score_id}', auth=(PUBLIC_KEY, SECRET_KEY))
