Error Downloading Albums Purchased With Separate Email

[OldZisty]

This is a user-ish error, but it may help someone in the future, so I figured I'd post anyway.

Some of my albums were purchased using a separate email. After running Bandcamp-Downloader, I noticed 5 errors like this:

"ERROR: An exception occurred trying to download file url []: 'content-disposition'(<class 'KeyError'>, KeyError('content-disposition'), <traceback object at 0x000001D1470220C0>)"

The fix is to simply add your alternate payment email to your account. More info here: https://get.bandcamp.help/hc/en-us/articles/360007803614-Some-of-my-purchases-are-missing-from-my-collection-What-do-I-do-

Perhaps the script could simply throw that information along with the error?

Hey, thanks for reporting this. That's interesting, and I'll have to play around and see if I can re-produce it to see what the API response looks like.

Hi @OldZisty, @easlice,

I was able to reproduce this error with one of the items in my Bandcamp collection.

Reproduction steps:

1. Send a GET request using a _url that has a payment email that is not associated with the logged-in session
2. The GET request to _url typically downloads a .zip file, however in this error case, content-length does not exist in the dictionary of response.headers.

As such, trying to execute expected_size = int(response.headers['content-length']) in line 345 returns a KeyError: {KeyError}KeyError('content-length').

Suggestion: we could try and catch the KeyError like so

            try:
                expected_size = int(response.headers['content-length'])
            except KeyError as e:
                print_exception(e, 'The GET request to {} failed to return a downloadable file for album {} by artist {}. \n'
                                     'Check that any your alternate payment email to your account.\n '
                                     'More info here: https://get.bandcamp.help/hc/en-us/articles/360007803614-Some-of-my-purchases-are-missing-from-my-collection-What-do-I-do-'.format(
                                     _url, _track_info['title'], _track_info['artist']))
