I am new to GPF development. For learning purpose, I tried to create a new band using bandmath operator. I am trying to read a Geotiff from a directory with 4 bands in it (band1, band2, band3, band4 and all of them are in unint8) and I want to create a new image by putting a condition on band1 i.e. band1 < 200 and I want to save the output in a Geotiff format.
My XML is attached here, and the error message is also attached here.
