xarray interp with method="cubic" fails for time/lon/lat interpolation

[mnergizci]

Hi, I am trying to interpolate a TEC DataArray using xarray:

tec_val0 = float(
    tecxr.interp(time=pretime, lon=lon0, lat=lat, method="cubic")
)

This work with 'method="linear"' but it never ends when I use 'method="cubic"'?

I am a bit confused as it was alright; just for couple of months ago

Is anyone experience same problem or any update?

Cheers,
MN

Can you please post a minimal complete code example that we can test? Thanks!
