Hi Darragh, the fact that the error message contains a '400' error suggests 
the problem happens on the server when it receives the report. 

My first guess given that error message is also that there's a mix of 
versions installed, but it's weird that it only happens on some reports. 
Maybe there is something malformed in those reports that triggers a 
different code path on the server.

You can save a copy of the reports by adding `store` to the type of report 
submission on the master: `reports = https,store` and see what they look 
like. They should go into a subdirectory 
of /opt/puppetlabs/puppet/cache/reports
