Project download returns empty 200 OK response

[jdrusso]

I have deployed webprotege using webprotege-deploy. Almost everything seems to be working -- I can log in, upload an ontology, modify it, etc.

However, trying to download the ontology with the button on the projects list page returns a blank page and no download.

I can see it's correctly making the GET request to what appears to be the correct url, .../download?project=<project_uid>&revision=<revision>, but there's no response.

Looking in the server logs, I see that it acknowledges the received request, and then nothing, no failures or anything.

When I compare the ProjectDownloadServlet in this repo against the one in the webprotege-server monolith, it almost seems like it's just missing the code after that logging statement that would trigger the download...

Is there a reason this was removed? Or, am I missing something?

Thank you!
