We were planning to migrate all our existing fivetran configurations to terraform . 
When i tried to import all the existing schema configurations , It gave me the below error : 

│ Error: Unable to Read Connector Schema Resource.

│

│ Error while retrieving existing schema. status code: 404; expected: 200; code: NotFound; message: HTTP 404 Not Found

So , when i through the fivetran terraform documentation . It has been mentioned that  Resource : fivetran_connector_schema_config is in Alpha state . 

Do you have this to be in beta version anytime soon . If so , Could you please share it . We will plan our work accordingly.
