[EP-tech] Elements/Eprints File Upload Refused

Hi James,
The Atom files are part of what Symplectic fires over to Eprints as part of the deposit process.
There is config options to keep/not keep them.

My initial hunch (from previous experience) would be that there is a character in the filename that is causing an issue - possibly an apostrophe.

Do you have a copy of the file being uploaded?

If not, you could try to upload a small (not empty) 'text.txt' file to the item.
If this does work , it probably is an issue with the filename of the real file being uploaded.
If it doesn't work, then there could be some incorrect XML data being sent (e.g. non UTF-8), or something else?

Let me know if the above file-based tests work or not - I can direct more about next steps from there.

Thanks for the pointer Alan. I took a look, but nothing jumped out at me.

I have since realised that the issue seems to be related to these two specific EPrints. Adding files to other pre-existing EPrints works with no problem. I had taken it at face value from a user that it had suddenly stopped working.

Suspiciously, there are over 20 Atom XML files, dated May 2017, in each of the two EPrints along with the pre-existing documents. I suspect these might be related to the problem.

Hi James,
I don?t know Elements but it looks from the level 2 and level 3 errors that the upload is causing EPrints to throw a server error (500) for some reason.  You may find more clues in the EPrints Apache error log?

My repository is EPrints based and accepts file uploads and metadata from Symplectic Elements.

Recently a colleague was attempting to upload a file through Elements to an existing EPrint that already contained documents. Unfortunately, Elements rejected the upload:

"An error occurred whilst uploading the file to the repository. Please reload the page and try again, or contact your system administrator if the problem persists."

Other files are still going through from Elements and for each attempted upload there is a corresponding xml file in the expected area of the repository server.

I have raised this as a ticket with Symplectic, but was wondering if anybody else had experienced this and might know what to do?

If anybody could give me some pointers as to how to solve this it would be brilliant.


Here is an example of the errors shown in Elements System Log (I've taken some bits out):
