Overview:
When uploading the zip file using the Multichannel Loader, an error appears: Zip file [filename.zip] is improperly structured. Please upload again. (Error 300) is being generated.
Root Cause:
The zip package being uploaded contains .png images which are not supported when using legacy packaging. Legacy packaging requires .jpg format.
Solution:
Update the packaging format to use the new standard for packaging files to upload using the Multichannel Loader.
Note: Folders should not be inside the zip file. CLM creates a folder called <filename> and unzips the contents of the zip into that folder.
