CDORemap: error at ecmwf machine?

Hi @aho (and @erifarov),

As you may have read at the issue https://earth.bsc.es/gitlab/es/requests/-/issues/2029#note_238031, CDORemap fails at ECMWF machine.

By running an example it returns the following error:

library(s2dv)
tas <- array(1:50, dim = c(25, 50))
names(dim(tas)) <- c('lat', 'lon')
lon <- seq(0, 360 - 360/50, length.out = 50)
lat <- seq(-90, 90, length.out = 25)
tas2 <- CDORemap(tas, lon, lat, 't170grid', 'bil', TRUE)
Error in CDORemap(tas, lon, lat, "t170grid", "bil", TRUE) : 
  CDO remap failed. Possible problem: parameter 'grid'.
In addition: Warning message:
! Warning: CDORemap: Using CDO version 1.9.8. 

I have been debugging the problem. The temporal file and path are correct. However, errobejct gets 1 after the interpolation, and I don't know what it means.

The tmp_file exists and can be opened. The tmp_file2 doesn't exist.

ls Rtmp7FABGs/

Do you have any suggestion?
