We migrated one of our services from CloudFuncitons to GCP CloudRun and started getting very weird errors during the first request to BigQuery API.
There are several typical errors:

com.google.cloud.bigquery.BigQueryException: Error writing request body to server
at com.google.cloud.bigquery.spi.v2.HttpBigQueryRpc.translate(HttpBigQueryRpc.java:115)

Errors disappear after several minutes/attempts of calling BigQuery and all work well until the next restart/redeploy of the service.

We introduced Retry mechnanism using external retry library as suggested here https://cloud.google.com/bigquery/docs/error-messages#connecterrors

But maybe there is another approach to avoid this service “startup” problems?

Do you know what can be the problem?

Thanks in advance!
