What it checks

The platform-account row’s stored URN must match ^urn:li:person:[A-Za-z0-9_-]+$. If we couldn’t mint a valid URN at connect time (or the row was edited), this rule fires before the upstream call.

​
Why this is a separate check

LinkedIn’s /rest/posts returns a generic 422 with no field path when the URN format is wrong. Catching it locally surfaces the actual issue.

​
Remediation

Disconnect and reconnect the account. The connect flow re-runs /userinfo to mint a fresh URN. If the issue persists, it’s a sign of an upstream LinkedIn bug — open a support thread with the request id.
