can't pickle _thread.RLock objects

I was going through the binder for the introduction part. For EOExecutor task, whenever the value for workers=3, I am getting an error. It is not allowing parallel process. It works fine for worker =1 & it should do but changing to greater than 1 is giving error.

`_RemoteTraceback Traceback (most recent call last)
_RemoteTraceback:

The above exception was the direct cause of the following exception:

Error: Getting the country's shape in polygon format (land_cover.ipynb)

I am getting a error in the "land_cover.ipynb" calling

country_shape = country.geometry.values.tolist()[-1]

AttributeError: 'GeometryArray' object has no attribute 'tolist'

Any idea why?

ValueError: During execution of task VectorToRaster: None is not a valid CRS

Hello,

For the water_level_extraction.ipynb, I get this error when executing the workflow. I check my geopandas version and it seems up to date.

Any ideas?
thank you!
