BigQuery data transfer job failed with following error message.
"Error code 7 : Invalid account; The issue may be resolved by verifying that the user has sufficient permissions and updating the credentials for this transfer config; error: "invalid_grant" error_description: "Invalid account""
As mentioned in https://cloud.google.com/bigquery-transfer/docs/cloud-storage-transfer, required permissions are given to the service account used for the transfer. Still getting this error.
