Import manifest issue

[trentwintermeier]

Describe the bug
First, last week this same issue was resolved. I went to check on the project and I noticed that, now, the audio nor video is showing up in AA. This is the first photo. Second, I went to "edit item" to include that information (to see if that was the problem) and received an error. This is the second photo. Finally, I tried to import the manifest again, but I am now receiving the same error as I did in my previous issue.

To Reproduce
Steps to reproduce the behavior:

1. Go to import

2. Type IIIF manifest

3. See error

4. Go to "edit item"
   2.. type information

5. See error

Expected behavior
To see audiovisual material on page; to see manifest uploaded successfully; for information to be applied to page and material
