RESTapi error while using dbx query any idea how to fix this?

curl -k -u rvanteru https://splunkang.brock.com:59447/servicesNS/rvanteru/splunk_app_db_connect/search/jobs/export --data-urlencode search='| dbxquery query=\"SELECT TOP 10 asof_date FROM perfdb.dbo_stat\" connection=\"Splunk_BFWD1\"'
Enter host password for user 'rvanteru':

Configuration initialization for /opt/splunk/etc took 192ms when dispatching a search (search ID: 1537295313.115513_FA99073F-7552-406E-ABE0-50BEE73D849C)
The 'dbxquery' command is implemented as an external script and may cause the search to be significantly slower.
