Ping Identity access certification failed: token endpoint returned invalid_grant error during review sync

TL;DR

Fix this in Ping Identity by acting on the exact message first: refresh or reissue the credential for the exact scope the failing call needs, store it in the run secret store, and retry one read call before resuming the full run. Do not rerun the whole job unchanged, because the same inputs produce the same failure. Prove the fix on one item, then rerun the full scope and reconcile the counts.

Ping Identity access certification failed: token endpoint returned invalid_grant error during review sync

Use this when

• The operation in Ping Identity fails with this exact message: Ping Identity access certification failed: token endpoint returned invalid_grant error during review sync.
• The same failure repeats on retry with unchanged inputs.
• A review, export or check is blocked until this item completes.

Not for this skill when

• The message is a permission or outage notice from the platform. Resolve that first, then return here if this error remains.
• The operation completes and you only disagree with its output. That is a quality review, not this failure.

Steps

1. Reproduce the failure with the smallest scope that still shows it in Ping Identity, and copy the full message plus the item, user or metric involved into the run notes. Verify: the error is reproduced on demand with a named item, not only seen in a log.
2. Apply the specific fix for this error: refresh or reissue the credential for the exact scope the failing call needs, store it in the run secret store, and retry one read call before resuming the full run. Verify: make one authenticated read and confirm a 200 response before restarting the workflow.
3. Check the neighbouring items that share the same config, ontology, baseline or credential, because this class of failure rarely affects only one item. Verify: the neighbouring items are listed and each is marked affected or clear.
4. Compare the result counts, decisions or alerts against the source in Ping Identity so a silent partial success is caught before sign off. Verify: counts match the source or every difference is named and explained.
5. Rerun the original operation in Ping Identity on the previously failing scope, watching for the same message rather than assuming success from a quiet log. Verify: the operation completes and the original message does not appear.
6. Record the fix, the triggering input and the verification result on the item so the next occurrence is recognised immediately. Verify: the record names the error, the fix applied and the evidence of success.

Why it happens

Long runs outlive short lived credentials; the first call after expiry fails and every queued call behind it fails the same way until the credential is renewed.

The how-to phrasing for the same failure in Ping Identity. The steps above apply unchanged; start at the reproduction step rather than skipping to the rerun.

Ping Identity troubleshooting for this failure

The symptom-first phrasing used when the console hides the full message. Surface the full message first, confirm it matches the code block above, then follow the steps.

Compatibility: Ping Identity at current versions, plus the platform API or console the query names; no extra tooling beyond a text editor and the source system access needed to verify counts.
