proxy returned malformed workflow job payload

Error message

proxy returned malformed workflow job payload

What it means

`_workflow_job_from` maps one workflow-job entry from the gh-proxy response into `WorkflowJobInfo`. If an entry is not a JSON object, the client raises `GitHubError(500, ...)` because it cannot safely read the expected fields. This is a client-side contract-violation error against the proxy's response format.

Solutions

1. Log/inspect the raw proxy response to see what the job entries actually look like
2. Align client and proxy versions (upgrade the robomp client or the proxy)
3. Bypass intermediaries (gateways, caches) that may replace the response body
4. If you control the proxy, ensure job list items are always JSON objects

Example fix

// before
jobs = client.list_workflow_jobs(run_id)  # GitHubError on non-dict entry
// after
try:
    jobs = client.list_workflow_jobs(run_id)
except GitHubError as e:
    log.warning("proxy job payload malformed", extra={"run_id": run_id, "err": str(e)})
    jobs = []

jobs_payload = fetch_raw_jobs(run_id)
if not isinstance(jobs_payload, list) or not all(isinstance(j, dict) for j in jobs_payload):
    raise ValueError("proxy workflow-jobs payload malformed")

def is_job_payload(v: object) -> TypeGuard[dict]:
    return isinstance(v, dict) and "id" in v and "run_id" in v

try:
    jobs = client.list_workflow_jobs(run_id)
except GitHubError as e:
    if "malformed workflow job payload" in str(e):
        log.warning("proxy job schema mismatch", extra={"run_id": run_id})
        jobs = []
    else:
        raise

When it happens

Trigger: `list_workflow_jobs` receiving a job list whose elements are strings/numbers/null instead of objects — typically a proxy version skew, an error page parsed as data, or a corrupted/partial response.

Common situations: Proxy upgraded to a new job schema while the client library is pinned old (or vice versa), reverse proxy or service mesh injecting error bodies, custom proxy implementations returning different shapes.

Understand the failure class

• Parsing and encoding errors: unexpected token, malformed input — why parsers reject input and how to find the real culprit.
