Dataflow refresh error for Google Big Query view

Hi Mukesh_Patel 

This error usually indicates that an internal error was encountered during the dataflow refresh process when using the Google BigQuery connector. Here are some of the possible solutions:

1. An unstable or interrupted internet connection may cause this error, make sure your internet connection is stable.

2. Increase BigQuery quota limits.

3. Adjust the incremental refresh policy from last 15 days to a shorter time period to see if this error can be avoided.

Please refer to the following troubleshooting documentation to see if it helps:

In the meantime, it is recommended that you get support from the BigQuery community to see if they have any good suggestions: cloud.google.com/bigquery/docs/getting-support
