Airflow BashOperator adds %27 to curl URL when templating dates

[assadali007]

I’m learning BashOperator to fetch data per day from the local API using data_interval_start and data_interval_end.

When the task runs, the rendered curl command contains an extra %27 (URL-encoded single quote) at the end of the URL, which breaks the request. on picture you could not when i click on the link on log %27 come to end it breaks the request

fetch_events = BashOperator( task_id="fetch_events", bash_command=( "mkdir -p /data/events && " "curl -o /data/events.json " "http://events_api:5000/events?" "start_date={{data_interval_start.strftime('%Y-%m-%d')}}&" "end_date={{data_interval_end.strftime('%Y-%m-%d')}}" ), dag=dag, )

No. it's the ' at the end is also copied to your browser and your browser converts it to url-encoded version when you click it - this has nothing to do with BashOperator. As explained in #60051 your iseeu is that you have no proper quoting of your command.
