I load data from BigQuery using Read(BigQuerySource(query="...", use_standard_sql=True)) in pipeline. On Cloud Dataflow, after about 3 minutes of run time, it will log an INFO of Attempting refresh to obtain initial access_token every few seconds until the end of job. How to fix it?

The same issue also affects GCS access. This is being tracked in https://issues.apache.org/jira/browse/BEAM-2264
