As the title says, when attempting to “start model run” after uploading specific road sources from my own files, I get a “there was a problem saving the model run” error and the run fails. As far as I can tell, the input files are clean, but obviously something is awry. Other files of mine work perfectly fine. I have uploaded the csv’s here for reference. For analysis parameters, I am doing - One hour concentrations - NOx, CO, and PM2.5 - Dynamic range (on) - Met station = KATL - Neutral, summer, seasonal avg, weekday, am peak Thanks everyone!

Looking through the error logs, the issue is the length of the “road name” value for a few sources. The road name for each source can’t be longer than 100 characters.
