I am getting the following error when I try exporting the simplest things. (A sphere and a light in this case)

Failed to save output to file “Traceback (most recent call last):
File ”/mnt/apps/rez_resource/htoa/htoa-5.0.2_raba8949_houdini-18.0.348/htoa-5.0.2_raba8949_houdini-18.0.348/soho/arnold.py“, line 14, in

verbosity = log_levels

Any ideas?

Thanks,
