agent failed to parse Aim query results after repo lock error failed to fetch runs

TL;DR

Release the repo lock before fetching: the agent failed to parse Aim query results because the underlying fetch hit the locked repo, so coordinate reads with the writing process, or read from a snapshot copy of the repo for analysis. The parse failure is downstream of a storage failure. Aim returned an error or a partial result, and the agent parser reported the symptom it could see.

agent failed to parse Aim query results after repo lock error failed to fetch runs

Use this when

• The check or run fails with this symptom: an agent fails to parse Aim query results after a repo lock error and cannot fetch runs.
• You are working on an agent workflow analysing Aim runs while training jobs write to the same repo and the failure repeats on the same data or configuration.
• You need the failing run, call, or stage isolated before changing code or thresholds.

Not for this skill when

• A repo with no writer that still reports locked, which is the stale lock case needing the lock cleared first.
• The error text names a different tool, stage, or root cause. Match the verbatim error first and use that skill.

Steps

1. Reproduce the fetch directly and read the raw response. Verify: the response is a lock error, not run data
2. Identify the process writing to the repo and its expected finish. Verify: the read can be scheduled after the write window
3. For repeated analysis, copy or snapshot the repo and query the copy. Verify: analysis reads succeed while training continues
4. Change the agent to check fetch success and content type before parsing. Verify: a lock error is reported as a lock error
5. Rerun the analysis. Verify: run results parse and summarise normally

Variant phrasings

agent parse aim query results repo lock failed fetch

The shorter phrasing focused on the named failure.

aim repo lock agent fetch runs error

The symptom phrasing a searcher tries next.

aim locked repo agent read fix

The variant naming the failing stage or tool directly.

Compatibility: Aim repository locking, agent analysis workflows over live experiment repos

Why it happens

Agents chain tools assuming each step returns what the next expects. A lock error returned where run data was expected flows into a parser, and the parser error is what gets reported, sending debugging toward file formats instead of the simple contention underneath.

Edge cases / pitfalls

• Validate every fetch by status and shape before parsing; parsers should never be the first place an upstream error is described.
• Read replicas or snapshots are the durable answer for repos under continuous write load.
