I recently this morning encountered an issue where for some reason the GUI on PAT had complete reset. In order to complete my analysis, I had to re-add various measures to the GUI. In order to access some of the measures, like "Apply Upgrade" that I needed, I reset the directory for "MyMeasures" to be the directory "Users\Username\Desktop\ResStock\OpenStudio-BuildStock-2.2.4\project_singlefamilydetached\measures."

Now, when running my analysis through AWS, I am getting "completed datapoint failure," with the following error in the log file:

[18:21:14.155226 ERROR] /var/oscli/gems/ruby/2.2.0/gems/openstudio-workflow-1.3.4/lib/openstudio/workflow/util/measure.rb 
failed with message cannot load such file -- 
/mnt/openstudio/analysis_8ff6431a-8991-4fd1-a4b8-65745f018ca8/measures/HPXMLtoOpenStudio/resources/constants in eval:107:in `require'
eval:107:in `require'

I suspect this has something to do with OpenStudio measures and changing "MyMeasures" directory, but I have no idea what the issue is. I have never seen this type of error in a PAT log file before, and I don't know how to interpret it. Please advise.

It sounds like you might not have the Additional Analysis Files correctly configured in your PAT project. See the ResStock documentation for what it should look like.

Thanks! I am unsure if Additional Analysis Files configuration was causing the problem. I managed to fix the issue by re-downloading PAT/OpenStudio and the ResStock files and then reconfiguring from scratch. Luckily this didn't take me too long because I have experience setting up an analysis, but it was a bit tedious, so I would recommend changing Additional Analysis Files if that is the cause of the error.
