Hey, all -

I would greatly appreciate any insight you have on uploading .epub files via iTunes Connect.

My most recent error message -


"1 package(s) were not uploaded because they had problems:
/Users/local/_______L/_____/Music/iTunes Producer/Playlists/9781614076056.itmsp - Error Messages:
Apple's web service operation was not successful
Unable to authenticate the package: 9781614076056.itmsp
ERROR ITMS-3000: "Line 311 column 99: character content of element "file_name" invalid; must be a string matching the regular expression "[^./: ]+([.][^./: ]+)+" at XPath /package/book/assets/asset[2]/data_file/file_name""

It looks like a filename problem, but I can't identify where it's originating. The Metadata all looks good in the OPF.

Any ideas?
