-----------------------------------
Summary: Incorrect type of query_params being required in
BigQueryOperator
Key: AIRFLOW-3855
URL: https://issues.apache.org/jira/browse/AIRFLOW-3855
Project: Apache Airflow
Issue Type: Bug
Components: api, gcp
Affects Versions: 1.10.2
Reporter: Ivan Ukhov
BigQueryOperator has been requiring query_params to be a dict for quite some
time. However, according to Google’s API is has to be a list:
https://cloud.google.com/bigquery/docs/reference/rest/v2/jobs#configuration.query
See configuration.query.queryParameters.
Prior to 1.10.2, it was not actually actually checked, and passing a list was
working fine. Since 1.10.2, it no longer works, as a check is in place and
raises an exception.
If one tries to pass a dict, as suggested by Airflow’s documentation, an
exception is raised on BigQuery’s side, as query parameters do not get through,
which is likely to be due to queryParameters (as a dict) being translated into
something that BigQuery does not understand.
