I searched in the forum solutions to the "ERROR: MODIS geolocation processing failed.", although all finf suggestions didn’t work.
I tried several input files, always with same result.
I work on "ocssw V2021.3"
In the following, the issue:

Percent valid data (0.00) is less than threshold (95.00)

Any suggestion will be appreciated

Here is the fix for the issue of "Percent valid data (0.00) is less than threshold". Please download https://oceandata.sci.gsfc.nasa.gov/ocssw/de200.eos and replace $OCSSWROOT/share/modis/static/de200.eos with it. You should be able to run modis_GEO.py then.
