>              Labels: convertjsontosql, putsql
> I am attempting to write a flat json object to my postgresql database using ConvertJSONToSQL
followed by PutSQL. My json has a string date field in ISO 8601 format which postgres can
accept as a timestamp. The column in the database is of type 'timestamp without time zone'.
> org.apache.nifi.processor.exception.ProcessException: The value of the sql.args.33.value
is '2017-02-01T23:12:21+00:00', which cannot be converted to a timestamp
> Is PutSQL trying to do some preprocessing here that it should just let the database handle?
> select  cast('2017-02-01T23:12:21+00:00' as timestamp without time zone);
>       timestamp
