Bug causing parser error in front which needs looking at

[olliencc]

when doing certain domains with all the generation options on seeing a couple of errors which I had to handle a fail condition for to allow the front end UI to complete. Need to investigate when I get time.

this this is in the back end. With the new logging now seeing this in the front end:

Error parsererror SyntaxError: Unexpected end of input

This is subtle and has taken a lot of tracking down as there's not an exception in sight... It appears to be caused because the backend sends the HTTP success headers before calculating the response. If the response calculation takes too long, then the web browser assumes the response is complete, and passes the still empty response body to the javascript.

Looks fixed now.
