Hi,
I recently installed ODK Build from source (https://github.com/opendatakit/build) on my Linux desktop (Ubuntu 18.04). The machine has plenty of resources - 24gb RAM, i5 quad core. Everything works swimmingly until I try to "Export to XLSForm". The export fails and the error and stacktrace below appear in the server logs:

and the message: "Something went wrong while exporting. Please try again later." in the browser
I have tried stopping and restarting the server several times. The server version given at startup is:
/media/storage/install/build-master/vendor/bundle/ruby/2.5.0/gems/thin-1.7.0/lib/thin/server.rb:107: warning: constant ::Fixnum is deprecated
Thin web server (v1.7.0 codename Dunder Mifflin)
When I open the same survey on https://build.opendatakit.org/ I can export the survey to XLSForm. Kindly assist.
