```
xarray.DataArray 'time' (time: 1) array([cftime.DatetimeNoLeap(2007, 7, 2, 12, 0, 0, 0, has_year_zero=True)], dtype=object) 

```
I updated your lines using @Hoeze' clear function and that seems to work for now. 


```[python]
    for v in list(ds.coords.keys()):
        if ds.coords[v].dtype == object:
            ds[v].encoding.clear()

    for v in list(ds.variables.keys()):
        if ds[v].dtype == object:
            ds[v].encoding.clear()
