500: internal server error on reading data files and on publishing worksheets
Since version 8.0 I encounter internal server error in the Sage Notebook when I try to read data files in "Data..." menu (worksheets were written and data files uploaded with older versions; fortunately, I still have version 7.6, so I can acess and work with data files).
I also encounter internal server error on publishing worksheets: worksheet is published, but "500: internal server error" message appears (so it is at least annoying).
I am using Sage binaries on 32 and 64 bits machines with Ubuntu Linux (sage-8.0/1/2-Ubuntu_16.04-i686.tar.bz2 and sage-8.0/1/2-Ubuntu_16.04-x86_64.tar.bz2). I also compiled 8.0 and 8.1 from sources. (With 8.2 there are problems with ncurses, but this is another story.) Sincerely, KF
I have the same problem in Sage 8.3 in a Debian 8 distro. The error mesage is:
Could not build url for endpoint 'worksheet_upload_data' with values ['id', 'username']. Did you mean 'worksheet.worksheet_upload_data' instead?
I found the problem seems to be in the following line of sagenb/flask_version/worksheet.py: upload_url = worksheet_upload_data.url_for(worksheet) But I do not know what it may be. Any help?
