Question

Uploading to LMS failed with error message. What project file changes are needed?

This error was received by the administrator when attempting to upload my zipped file into the LMS.  I'd like to edit my course as necessary to make correct the issue, but I don't know what it means...or what changes I can make to help ensure success.

I am using Cp 9 - version 9.0.2.437

Here are the first clauses of the error message:

"Error: Failed to unzip: Could not Unzip file System.IO.InvalidDataException: End of Central Directory record could not be found. at System.IO.ZipArchive.ReadEndofCentralDirectory..."

 

Tried to upload a small image of the error msg to this post...ironically, an error occurred in that upload w/ a try again msg - tried again 5 times:-(

How are you delivering the ZIP file to your LMS Administrator? I used to work for a company that had security on their email server that would disable all Javascript when trying to email a published course. This had the effect of rendering the package unusable by our LMS and would give us errors. In this case, the solution was to manually walk it over to the LMS coordinator using a USB thumb drive.

It is being uploaded to SharePoint, and the LMS Handler uploads it from there.

eLearning contains code that is executed so your company's network might be interpreting the package as a potential threat and neutralizing the executable portions of your project. Maybe worth walking it over to your LMS Admin by hand and seeing if that could be the problem. I wouldn't be surprised if your system strips out anything that could potentially be some form of malware.
