LOCK_NOT_ACQUIRED
A distributed lock could not be acquired; the operation is safe to retry.
HTTP status: 503
What it means
A distributed lock could not be acquired; the operation is safe to retry.
Why it happens
- A concurrency lock (idempotent create, image-cache fill) stayed busy past the wait budget.
How to fix it
- Safe to retry — the operation did not run.
Example
