Because * the fetch task used experiment status and a fixed time window to decide when to fetch results * #15871 changed this to fetch whenever an experiment has newer results, but was reverted in #16152 after invalid metadata for older experiments crashed the fetch loop This commit * reland the reverted #15871 changes that fetch results when an experiment's analysis start time is newer than the stored one Fixes #15737
Because * Jetstream writes metadata for some older experiments that is missing fields the current schema requires (e.g. analysis_bases) * validating that metadata raises a ValidationError that we do not catch * this crashed the whole fetch loop and is why #15871 was reverted (#16152) This commit * report the error to Sentry and skip the experiment instead of raising, in both the main loop (get_latest_analysis_start_time) and the fetch task (fetch_experiment_data), so invalid data is never stored or surfaced and one bad experiment cannot abort the fetch for the others * add tests that reproduce the schema validation error reported in Sentry Fixes #16203
