Sometimes the following errors occur when attempting to upload files via the Producer Portal user interface or when submitting loadFileImage transactions.
"There was an unexpected error while copying the file into master storage. (Code: SM)"
"There was an unexpected error while copying the file into master storage. (Code: MC)"
These errors typically occur when the file is still in the process of loading to the FTP upload server (upload.flexnetoperations.com). The solution is to wait until the file finishes loading to the FTP before attempting to upload the file.
