Importing Package using module loader, but list view shows Data not available.

Maybe the module builder did not load the file correctly or your session ended or there is an error in the compilation of the file.
Update the page or your session.
Try to reload the zip

Hi Amy Cox, 

You're missing the language file & folder in your package, which is probably why.

The language file usually adds the module to the "moduleList", which the application uses to find whether a module exists or not. 

It should have something like:

$app_list_strings['moduleList']['Lev_Course_Catalog'] = 'Lev_Course_Catalog';

Once you add the language folder try uploading the zip again, it should work. 

I really thought that would fix it, but I am still having the same error.Course_Catalog2020_09_02_Amy.zip

Since the previous upload didn't have a language, that may have left incorrect data in the lang folder. Are you on Cloud or On-Premise? 

Can you check if there is a file or folder with this name: custom/Extension/application/Ext/Language/en_us.Course_Catalog.php

If you don't have access to the folder, you can also try changing the $installDefs['id'] field to something else and try installing again.

Good news!  There was a folder called en_us.Course_Catalog.php where you mentioned.  I deleted it, then went to module loader and uninstalled Lev_Course_Catalog and reinstalled it and it worked.

This is the second time I have seen a folder where a file should be.  I am guessing it is a side effect of copying a file that doesn't exist.

Thank you so much for your help.
