@Jamie Iong​ : It looks like the issue you're encountering is due to how the quotes are being escaped. In the command you provided, the backslashes before the quotes are getting interpreted as part of the argument rather than as an escape character. Try using single quotes around the JSON string and double quotes inside the JSON string to encapsulate the key-value pairs. For example:

databricks jobs run-now --job-id 1 --notebook-params '{"key":"value"}'
