QSWAT is having trouble writing the .sol files when building my SWAT2012 model (See attached screenshot). I believe my SSURGO soils raster is appropriately processed for QSWAT (following this tutorial -- https://swat.tamu.edu/media/116594/us_soilsv3.pdf) but when QSWAT tried to write the .sol table I got an error. This is likely due to a few SSURGO MUKEYs in my watershed not being within the SSURGO database. I've tried removing these soils but am still getting this error.
Does anyone know how to remedy this issue? Or could someone write out how they cleaned up their SSURGO soils to ensure they interact with the SSURGO database correctly?

Hello,
Which version of the "SWAT_US_SSURGO_Soils.mdb" you are using?
I recommend using the 2019 version, as other versions may have compatibility issues.
Thank you!
