How to save biascorrected grids?

[Fisico2k]

After biasCorrection command, I need to save the resulting grid in netCDF format. I use grid2nc command and the file is correctly created. But when I try to reopen ti with loadGridData there is this error:

Error in .jcall("RJavaTools", "Ljava/lang/Object;", "invokeMethod", cl, : java.lang.ArrayIndexOutOfBoundsException: Index 3 out of bounds for length 3

Actually, I note that files correctly opened by loadGridData (i.e. ESGF model outputs) have this output:

dataInventory("path_to_file")
$pr =
$Description
'Precipitation'
...... etc........
$Dimensions
$time
...etc....
$lat
...etc...
$lon
...etc...

On the contrary files from bias-corrected grids have this type of output:

dataInventory("path_to_file")
$pr =
$Description
'Precipitation'
...... etc........
$Dimensions
$lat
...etc...
$lon
...etc...

It seems theere is no time dimension and the error seems to depend on it (Am I right???).
But time data are actually presente in the grid! Only the format is different indeed.
It is so:

$Dates
$start
'2021-01-01 UTC'.....................

Otherwise in "ordinary" grids it is so:

$Dates
$start
'2021-01-01 12:00:00 GMT'.....................

Anybody can help me to try to solve?

your bias adjusted grid variable data shoud be a 3D array with dims time lat lon. What are dimensions of the grids going into biasCorrection?
