Can't initialize BigQuery connection - "Headless Exception" error

That was it! I removed the grpc-api-*.jar file, rebuild the image and reinstalled the helm chart.So why did I not followed a procedure [1] properly?At first I worked with the non-offcial dbschema.com drivers and than switched to the offical drivers.And I admit I had not taken the step 3 seriously. To me “Execute the following script to delete the libraries that aren’t required for JDBC functionality:” had read like an optional step – rather than a mandatory one that would cause serious errors if one ignores it.So probably a clear statement about the error potential would be a helpful improvement of the docu.Thanks @jacek and @Robert Moucha and @Dominik Labuda for your help![1] https://www.gooddata.com/developers/cloud-native/doc/1.3/administration/data-sources/supported/bigquery/#prerequisite

Can't initialize BigQuery connection - "Headless Exception" error

For us, it works fine with the older version 1.2.4.1007 as well as with the latest 1.2.19.1023. You’re using 1.2.16.1020 so I guess it should work as well.   Okay, so we tested in k8s setup with 1.2.14.1017 and just now also with 1.2.19.1023. Both downloaded from https://storage.googleapis.com/simba-bq-release/jdbc/SimbaJDBCDriverforGoogleBigQuery42_1.2.14.1017.ziphttps://storage.googleapis.com/simba-bq-release/jdbc/SimbaJDBCDriverforGoogleBigQuery42_1.2.19.1023.zipBoth produce the same kind of exceptions..It says “HeadlessException” in the thread title… the actual exceptions @dastein and me get look like this though (see below).Any ideas..? {"ts":"2021-08-26 11:15:05.325","level":"WARN","logger":"com.github.benmanes.caffeine.cache.LocalAsyncCache","thread":"DefaultDispatcher-worker-2","traceId":"04a19400a60fde7e","spanId":"99ffe5696ee014b8","userId":"jku","orgId":"syn","msg":"Exception thrown during asynchronous load","exc":"java.util.ServiceConfigurationError: io.grpc.ManagedChannel

We tried to reproduce your issue in our K8S deployment with multiple replicas of sql-executor, but everything is working properly on our side so far. We are digging deeper and will let you know once we find something interesting. Hi!Could you please provide the link to the exact driver/version you are using for BigQuery so we test with the exact same one?Best - j
