[GRASS-dev] ERROR: no null file for <rasterxxxx>

I am opening a new raster file of nrows >100 and ncols > 100
writing a single row with values then closing the file.

It gives me this error.

"ERROR: no null file for <rasterxxxx>"

Any possible way to get through it,
close the file properly and not getting this error?

I have been trying to create a raster first, filling it with 0.0 and then
closing it. But this does not influence Rast_open_new() since it is not
connecting to the same name raster file existing on disk as long as it does
not actually write the new raster to disk. The failsafe "ERROR: no null
file for <rasterxxxx>" maybe called too early as it does not check for
pre-existing file on disk with same name...

any help please?
