We are trying to connect Celonis4.7.2 (onprem) to the GCP using the BigQuery Simba JDBC Driver supplied by Google. 

The .jar files have been unzipped into <installDir>\\lib but trying to connect from the frontend, we encounter the following errormessage:

Has anyone successfully connected Celonis4.7 (or any other onprem version) to the GCP?

Thank you for your help!

Cheers,

Felix
