Hi @dream81, this is just an input format error in the template. I believe it's here:

mintpy.load.waterMaskFile = None

It should be auto if you want to ignore the water mask.

mintpy.load.waterMaskFile = auto

By the way (not related to this error you report), your filenames for isce output files are weird. This could result in a further issue while reading the files in loading data.

mintpy.load.unwFile = ../merged/interferograms//filt_.unw
mintpy.load.corFile = ../merged/interferograms//filt_.cor
mintpy.load.connCompFile = ../merged/interferograms//filt_.unw.conncomp

I remember in isce, the default output is put into date12 folder and named as filt_fine.unw, filt_fine.cor, filt_fine.unw.conncomp. So unless you intentionally name your files and folder that way for your test dataset, these entries should look like:

mintpy.load.unwFile = ../merged/interferograms/*_*/filt_fine.unw
mintpy.load.corFile = ../merged/interferograms/*_*/filt_fine.cor
mintpy.load.connCompFile = ../merged/interferograms/*_*/filt_fine.unw.conncomp
