Odd bug. I can only reproduce it on a single page and only on officewiki, but it seems to be persistent on that page. (I tried to reproduce in other namespaces, and in mw.o and enwiki, but it worked properly there)
- Open this gdoc
- copy the 1 line
- Open this this officewiki page
- Click "Edit" to open VE.
- paste the text.
- Try to either "switch to source editing" or to "publish changes", and see the error message(s).
Switch to source = Error loading data from server: Error contacting the Parsoid/RESTBase server (HTTP 500)
Publish changes = Error contacting the Parsoid/RESTBase server (HTTP 500)
