unable to load data into big query table by BigQueryOperator in composer - google-bigquery

Question

I have created the dag to load the data from big query to another big query table. I have used the BigQueryOperator in composer . But this code is not working as expected. I'm not able to get the error can any one please help me resolve this issue.
And i manually created empty table also still data in not loading into the table.Please find the below code and let me know did i missed any thing?
from typing import Any
from datetime import datetime, timedelta
import airflow
from airflow import models
from airflow.operators import bash_operator
from airflow.operators.python_operator import PythonOperator
from airflow.contrib.operators.bigquery_operator import BigQueryOperator
sql="""SELECT * FROM `project_id.dataset_name.source_table`"""
DEFAULT_ARGUMENTS = {
"owner": "Airflow",
"depends_on_past": False,
"start_date": datetime(2019, 8, 7),
"schedule_interval": '0 6 * * *',
"retries": 10
}
dag = models.DAG(
dag_id='Bq_to_bq',
default_args=DEFAULT_ARGUMENTS
)
LOAD_TABLE_TRUNC = BigQueryOperator(
task_id ='load_bq_table_truncate',
dag=dag,
bql=sql,
destination_proect_dataset_table='project-id.dataset-name.table_name',
write_disposition='WRITE_TRUNCATE',
create_disposition='CREATE_IF_NEEDED',
allow_large_results='true',
use_legacy_sql=False,
)
LOAD_TABLE_APPEND = BigQueryOperator(
task_id ='load_bq_table_append',
dag=dag,
bql=sql,
destination_proect_dataset_table='project-id.dataset-name.table_name',
write_disposition='WRITE_APPEND',
create_disposition='CREATE_IF_NEEDED',
allow_large_results='true',
use_legacy_sql=False,
)
LOAD_TABLE_TRUNC.set_downstream(LOAD_TABLE_APPEND)

Answer 1

This is to find out error specific to the DAG's failure
You can find out error in two ways
Web Interface:
Go to the DAG and select Graph view.
Select the task and click on View Log.
Stack Driver logging:
Go to this URL https://console.cloud.google.com/logs/viewer? project=project_id.
Select 'Cloud Composer Environment' from first dropdown followed by location and DAG name.
Select Error as from Log level dropdown.

Answer 2

As Josh mentioned in his comment on your post, the value for allow_large_results should be True without the quotes. Additionally, I see that you have a typo in your spelling of destination_proect_dataset_table. You're missing a 'j': destination_project_dataset_table
BVSKanth's recommendations for finding DAG errors are also spot-on and worth considering for future debugging.
