I'm using ArcGIS Pro 3.0 to process a series of .tif files. I'm going to process these images in a program that requires NoData and nan values to be set to a numerical value, like -3. I have code to set these null values to -3, and it works when the output is a geodatabase object, but not when I save it. When I save it to a file folder, it does not change the NoData values at all. Why does this happen, and how can I get my saved outputs to have changed NoData values? Here is my code:

 

from arcpy.sa import *
inras = r"G:\My Drive\work\Northern Animal Ecology Lab\sentinelrst\rst2019\bl\20190129.tif"
outCon = Con(IsNull(inras), -3, inras)
outCon.save(r"G:\My Drive\work\Northern Animal Ecology Lab\sentinelrst\rst2019\20190129null.tif")

I suspect the raster byte type change during the process
