Cdata Error : Could not create connection to database

I am using Json Input node and posting input parameters as json, The problem is when i connect table column to variable node that have a variable from the json input with database connector i get the error

"Execute failed: Could not create connection to database: cdata.jdbc.googlebigquery.GoogleBigQueryDriver"

But when i not post any json then it execute successfully with default values that is set in the Json Input node.

Attached: workflow snapshot

Please help to find what is going wrong ?

Hi Isabir,

is this driver available on the server as well?

Best, Iris

Yes, When i not post json variable to workflow, It run successfully with the default values. It mean drivers are available and installed.
