'cluster_url' must be one of: [<class 'str'>], but got <class 'NoneType'>

‘cluster_url’ must be one of: [<class ‘str’>], but got <class ‘NoneType’>

what`s going on here? I got my cluster_url , but cannot use it

hi @bo_sun ! Welcome to our community :hugs:

Can you share some more code?

My bet is that if your are using a variable to define the cluster_url, it’s not working, as the client seems to be complaining that you passed a None value as the cluster_url, instead of a string.

Can you try replacing this variable with the actual value of the url, or print this cluster_url before passing it to the client?
