When using the cmdlet Get-VaultFileBom on an assembly the error 1013 is thrown. This Error means "GetFileFailed: Cannot get file (file id is invalid)".
This issue could happen if Purge is used in Vault as it deletes specific file versions.
There are different ways to get rid of this issue:
Re-Check in the assembly in Inventor
When you check out and re-check in the problematic assembly it will regenerate the BOM and the error will disappear. this can be quite time consuming on large assemblies.
