Getting "DEM Missing Data! Needs Further Adjustment." Error

[AeroSteveO]

I'm trying to run with the following in the downloadlist.txt file:
https://rockyweb.usgs.gov/vdelivery/Datasets/Staged/Elevation/LPC/Projects/WI_Statewide_2018_A18/WI_FondduLac_2018/LAZ/USGS_LPC_WI_Statewide_2018_A18_0339.laz

and am currently getting the following output:

Generating .dtm files...


Generating .asc files...

[]
DEM Missing data!  Needs further adjustment.  Setting lowest value to 0.
Cleaning up...

This is also not outputting any STL files to the STL folder or other output files that i can find. Any help would be appreciated.

Details about what i'm running it on:
Python 3.8.10 on WSL2.0 ubuntu machine, also tried using the .exe on a windows 10 machine to the same output

ahh my .laz files aren't being downloaded by the widget, and also aren't following the naming conventions so its being skipped

got things downloaded, using the -e flag and the files in the LAS directory, but still no dice

wait, now got things running, using the windows .exe rather than the python script, woo
