SYMPTOMS:

infoRouter uses warehouse paths to store document contents and other meta files.

When a document content storage location in a warehouse is inaccessible, corrupted or not found this error will occur.

RESOLUTION:

If you think the warehouse path (example P231312) is corrupted or missing you may restore the specific warehouse path from the latest backup.

If this problem occurs right after a warehouse migration or restore operation make sure you restored matching warehouse and database backups. If required restore again.
