Add error handling for jsonPathString UDF when jsonPath is non-existent #7439
Description
If you use "non default value" version i.e jsonPathString(Object object, String jsonPath) then there is no error handling in case jsonPath doesn't exist and will cause data ingestion to fail. Need to return null in such scenarios so data ingestion is not impacted.
Similar to above function other functions for e.g jsonPathDouble() etc. need to be updated as well.
