agent failed calling Aim storage API failed 500 internal error on sequence fetch

TL;DR

Treat the 500 as a server fault and retry with evidence: the Aim storage API returned an internal error on a sequence fetch, so capture the request and time, retry after a pause, and if it persists, report it as a server issue with the failing sequence identified. A 500 is the server admitting fault. The agent job is to prove it is not the request, preserve the details, and avoid hammering a struggling service.

Use this when

• The check or run fails with this symptom: an agent fails calling the Aim storage API with 500 internal error on sequence fetch.
• You are working on an agent workflow fetching metric sequences from a self-hosted Aim server 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 500 triggered by one pathological sequence, such as an extremely long history, which needs that sequence isolated rather than a service ticket alone.
• The error text names a different tool, stage, or root cause. Match the verbatim error first and use that skill.

Steps

1. Repeat the fetch for a different sequence on the same run. Verify: other sequences return, isolating the fault, or all fail, indicating a service wide problem
2. Check the Aim server health and its logs for the request time. Verify: a server side exception is recorded for the failing request
3. Retry the original fetch after a pause. Verify: the fetch succeeds, or the failure is consistent and reportable
4. If one sequence consistently fails, fetch its data in step ranges. Verify: the sequence is recovered in parts or the failing range is pinpointed
5. File the failure with the sequence identity, the request, and the server log reference. Verify: the report is actionable by whoever runs the server

The variant naming the failing stage or tool directly.

Compatibility: Aim storage API, self-hosted Aim server operations, agent error handling

Why it happens

Self-hosted tracking servers fail in ordinary operational ways: a storage backend hiccup, a memory limit on a huge sequence, or a version bug. Agent code that treats a 500 like a client error either loops forever or reports the run data as missing, when the data is fine and the service needs attention.

Edge cases / pitfalls

• Backoff on 500s must be real: repeated instant retries can keep a struggling server down.
• Distinguish server faults from missing data in every summary, or teams will rerun good experiments.
