In implementing pandas-gbq integration with the new, faster query_and_wait method, a test failure raised the issue that some request body details in a custom job configuration are being dropped. See: https://github.com/googleapis/python-bigquery-pandas/pull/722/files/7739f41989c5d0effbaf66070c6b94b6c3840506#r1459296431

Steps to reproduce

  1. Create a QueryJobConfig with unknown or invalid parameters via from_api_repr()
  2. Pass the job_config to query_and_wait().
  3. Observe that the extra parameters are not sent.

Code example

import google.cloud.bigquery
client = google.cloud.bigquery.Client()
project_id = "swast-scratch"

job_config = google.cloud.bigquery.QueryJobConfig.from_api_repr(
        {
            "copy": {
                "sourceTable": {
                    "projectId": project_id,
                    "datasetId": "publicdata:samples",
                    "tableId": "wikipedia",
                },
                "destinationTable": {
                    "projectId": project_id,
                    "datasetId": "publicdata:samples",
                    "tableId": "wikipedia_copied",
                },
            }
        })
client.query_and_wait("select 1", job_config=job_config)

Stack trace

No stack trace is produced, even though one should be due to an invalid configuration.
