[GRASS-user] ERROR 1: TIFFOpen: No error Using GDAL data type <Byte>

[umberto.minora]

I am using "r.out.gdal" function within a Python script through the command
console of grass7.
I am calling it by doing:

{{{
from grass.script.core import run_command

run_command("r.out.gdal",
				flags="c",
				type="Byte",
				input="prova"+ str(m+1),
				output=outFolder+ "\prova"+ str(m+1)+ ".tif",
				nodata=255)
}}}

I am getting this error:

{{{

}}}

Anyway, if I use the same call from the command line (not calling the Python
script) I have my "prova1.tif" written correctly in the folder I chose. Why?
Any guess?
