Energyplus 8.9 crashes after using updated 8.8 idf file

I have an idf file I created and used in energyplus 8.8 but when I switched to 8.9 and updated the 8.8 idf file the simulation just crashes. Normally I would have the error file to work with to fix my idf file but this crash leaves me little clue as to what is wrong. I tried running the 8.8 idf file in EP8.8 again and it works there, with no errors. I compared the 8.8 and 8.9 idf files in the idf editor and there are no differences, meaning the update of the file seems ok. I suppose the new EP does not like something about my idf setup which was previously fine.

I ran the simulation with the "pause" function and at the end of the simulation I get this:

C:\Users...\EPTEMP-00000001>IF NOT EXIST eplusmtr.inp "C:\EnergyPlusV8-9-0\postprocess\ReadVarsESO.exe" test.mvi ReadVarsESO program starting. EOF encountered during read of ESO header records probable EnergyPlus error condition -- check eplusout.err ReadVarsESO program terminated. ReadVars Run Time=00hr 00min 0.03sec

ERROR: ReadBND, Did not recognize: Non-Parent Node

What could the problem be?

Did you run version translation in E+? tried re-installing 8.9? checked the E+ release notes for changes If all that doesn't work, post the .idf here and submit it as an issue on the E+ github.

I did run version translation in E+ and reinstalled 8.9, still the same issue. I did not see anything related in the release notes but I could be missing something. I tried playing around with the HVAC definitions and was able to get it to run with error messages. Once I fixed the last error message (missing thermostat in the HVACTemplate:Zone:VAV) and ran the simulation, the same crash occurred again.

Here is the idf file

This is tripping on a known problem in v8.9.0. See issue #6860 "Crash in table reports with SizingPeriod:WeatherFileConditionType as the only type of sizing period" for more details and workarounds.

This solved my crash issue but now I am dealing with fatal error message of limited information:

*** Warning: Node connection errors not checked - most system input has not been read (see previous warning). *** Fatal error -- final processing. Program exited before simulations began. See previous error messages.

Still looking into this - any suggestions welcome.

What's the real severe/fatal error that comes before this?

This was the beginning of the error log, no description of the fatal error, which was strange/not helpful.

I figured it out though. When removing the 'ZoneComponentLoadSummary' from my reports to solve the #6860 issue I just substituted the 'Report # Name' with the '<blank>' from the dropdown list, which appears to cause this unidentified fatal error. Recreating the output object without any blanks fixed it.

That's not very helpful. New issue #6919 posted.
