I tried with single quote wrapping with double quote inside:

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

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

databricks jobs run-now --job-id 1--notebook-params "{\"key\", \"value\"}"

But I got these corresponding errors:

Error: JSONDecodeError: Expecting property name enclosed in double quotes: line 1 column 2 (char 1)

Error: Got unexpected extra argument (key, value})

Error: Got unexpected extra argument (key\, \value\})
