Some of the bands within the source datasets had None as the no data value. Additional check within the code is required to ensure that nodata_mask is updated to a value 255 for a negative integer values only.
Also, the files referenced within qsub-cog app is relative meaning the same app does not work as expected when we run the qsub-cog command from a different directory. To solve this, make all the file references within the app as absolute.
Proposed solution
Update nodata_mask to a value 255 only when we have negative band value.
Make changes to glob the relative pattern for *.tif or *.TIF files and *.nc or *.NC files.
