Measure Manager Crash Error with OS:Coil:Heating:DX:SingleSpeed EIR(FlowFraction) Curve

I already asked this question in the following issue on OpenStudio Github page, but thought I would post it here also in hopes that I would get more responses.

Using OpenStudio 2.7.0 x64 on Windows I get the following error in the stderr file when trying to simulate the model. I also get this error when trying to drag a new measure over from Library on Measures Tab (refer to linked error screenshots below). Additionally, the simulation fails when trying to run in PAT. This error doesn't occur in model files without DX coils.

Through the help of David Goldwasser with my GitHub Issue, I was able to figure out the issue. It appears that when I used the "Create Baseline Building" measure, it created System Type #4 PSZ HPs without a curve assigned for the Energy Input Ratio Function of Flow Fraction Curve Name field. Therefore, to fix the error I assigned a curve to all of those systems and now the model works fine. See below for an example of one of these systems that were created by the measure.
