@jim12321 I got the same error with CLI version 0.223.1, but I could resolve it by escaping the quotation marks:

databricks jobs run-now --json '{\"job_id\":85218616788189,\"notebook_params\": {\"demo\":\"parameter successful\"}}'

Seems to be fixed by the databricks team with version 0.223.2 and using CLI version 0.208 your provided command works fine too.
