Hi @tonyd Thank you for reaching out to the Databricks Community.

You are trying to create a Serverless Generic Compute Cluster which is not supported. You cannot create a Serverless compute Cluster.

As per the below link, if you observe, there is no parameter like "enable_serverless_compute". you cannot use this in the Cluster create API

https://docs.databricks.com/api/workspace/clusters/create

But you can create a Serverless SQL Warehouse where you can also use the parameter "enable_serverless_compute". You can observe this param in the below link which is Warehouse create API,

Please leave a like if it is helpful. Follow-ups are appreciated.

Kudos,

Sai Kumar
