Hi I need to validate custom fields and throw exception for before Issue creation submit

in JIRA cloud...

There's no way to do this in Cloud.

On Server, you could use the Behaviours module in ScriptRunner to inject the javascript that could do validation before submit, but Cloud does not support this sort of thing yet.
