infoRouter uses warehouse paths to store document contents and other meta files.
This error condition occurs when infoRouter tries to read meta file in the document path and cannot find the meta file or in cases where the file is found but it is unreadable. The meta file should be a properly formatted XML document which can be parsed into valid components.
Look at the error details to determine the document id.
Make sure that the warehouse configuration points to the correct path.
If you have performed a migration or restored the warehouse make sure that the restore matches the database from the same backup
Contact infoRouter support if you are unable to determine the cause of the problem
