Have a survey that is meant to be opened using the inbox to view current features and submit a pass/fail on them. On a very small percentage (few dozen out of thousands) some users are getting a "500 Error: Attachment does not have contentType". 

The layer is a feature service coming from an SDE so I opened up the attachment table expecting to see some null values in the content type field but everything was present.

Here are the attachments for one of the features that is giving the error. They all appear in the inbox as existing photos. Any ideas on this would be appreciated!

We had this error couple of times. for us it happened on edit an existing form that has an attachment. The dev tool shows that the form tried to reupload the file, no idea why. I can download the attached PDF and open it fine. finally fixed it by deleted the attachment. save the form. reopen the form and attach the PDF again.  one of the many annoy bugs in survey123.
