Ingesting wrapped interferogram from topsStack causes an error

[bjmarfito]

Description of the problem

I loaded wrapped interferograms generated from topsStack using smallbaselineApp.py and it causes a loading error

Full script that generated the error

smallbaselineApp.py --dostep load_data

Full error message
