While trying to upload an image, I got this in the iframe:
<?xml version='1.0' encoding='UTF-8'?>
<Error><Code>InternalError</Code><Message>We encountered an internal error. Please try again.</Message><Resource>Failed to get necessary short term bucket lock for mbid-80e39d32-3902-431f-83bf-6902c1761fff, please try again</Resource><RequestId>ade67eb9-6d10-4619-a7f2-696b7534ba0a</RequestId></Error>
I realise this is probably something on archive.org's side that we can't fix, but we could handle it better. Printing a bunch of XML is not very user-friendly and it would be really nice if the filename wasn't lost because now I have no idea which image I need to try reuploading.
