Reappearance of AttributeError: 'SpooledTemporaryFile' object has no attribute 'seekable' about blackboard-scorm-analysis

[zaript]

The fix seems to be to change line 77 in server.py:

			# zip = zipfile.ZipFile(file.stream)
			zip = zipfile.ZipFile(file)

The upload works normally with this fix, but then there is an issue with interpreting module archive:

This is not an original issue anymore, but I will update the thread just in case someone needs it. Our BlackBoard archived course with an error, that seems to prevent this Analysis tool from opening a particular SCORM package in the archive. The workaround I have used is to skip the package with an error from loading.

Changes to line 260:

# item.subitems = [self.load_item(subelement) for subelement in element.xpath('item/item')]
item.subitems = []
for subelement in element.xpath('item/item'):
	try:
		item.subitems.append(self.load_item(subelement))
	except:
		print("***** failed to load subelement ", subelement)

This way I can still load and analyse the remaining part of the course.

I ran into these same issues in August 2022. I tried the bottom fix first (line 260) but it didn't work. Then I included the zip fix too (line 77) and it worked!
Thanks
