Airflow 無效 arguments 和關鍵字參數

Question

使用 GCSToBigQueryOperator 發生此錯誤

Broken DAG: [/opt/airflow/dags/injest_data.py] Traceback (most recent call last):
File "/opt/airflow/dags/injest_data.py", line 79, in <module>
>     "sourceUris": [f"gs://{BUCKET_NAME}/*"],
File "/home/airflow/.local/lib/python3.7/site-packages/airflow/models/baseoperator.py", line 397, in apply_defaults
raise AirflowException(f"missing keyword arguments {display}")
airflow.exceptions.AirflowException: missing keyword arguments 'bucket', 'destination_project_dataset_table','source_objects'****

當我嘗試更改為 BigQueryCreateExternalTableOperator 時，會發生其他錯誤

在此先感謝您的幫助...

我曾嘗試更改谷歌查詢運算符，甚至嘗試使用不同的方法將數據上傳到 bigquery，但說模式不存在，請幫助我了解哪里做錯了。 在此先感謝您的幫助，以下是導致錯誤的代碼

    bq_external_table_task = BigQueryCreateExternalTableOperator(
            task_id = "bq_external_table_task",
            tables_resouces = {
                "tableReferences": {
                    "projectId": PROJECT_ID,
                    "datasetId": BIGQUERY_DATASET,
                    "tableId":f"{DATASET}_external_table",
                },
                "externalDataConfiguration": {
                    "autodetect": True,
                    "sourceFormat": f"{INPUT_FILETYPE.upper()}",
                    "sourceUris": [f"gs://{BUCKET_NAME}/*"],
                },
            },
            
        )

GCSToBigQueryOperator中沒有sourceUris命名參數。 它應該有source_objects 。 請從以下官方文檔中檢查運算符的參數： GCSToBigQueryOperator

您的BigQueryCreateExternalTableOperator也有錯誤的參數名稱。 tables_resouces應該有table_resource 。 您也可以從官方文檔查看此運算符的參數： BigQueryCreateExternalTableOperator
