Error Using StripmapApp.py

[arnavgarg233]

When I try to use StripmapApp.py on SENTINEL-1 data, the object, sensor, is missing a variable and isn't initialized properly. My SENTINEL-1 data is obtained from the Alaska Satellite Facility(ASF) website, with satellites that carry C-band SAR data. The code block above is the error logs that I receive when I run StripmapApp.py, and the bottom code block is located in runPreprocessor.py where sensor is defined. I wanted to know where self.reference is defined, since that seems to be how sensor is defined based on the second code block. Alternatively, if anyone knows how to fix the issue I would really appreciate it.
