FivetranOperator stuck in deferred state till it times out

[dgrewal-tc]

Apache Airflow version

Other Airflow 2 version (please specify below)

If "Other Airflow 2 version" selected, which one?

2.9.2

What happened?

This is in relation to astronomer/airflow-provider-fivetran-async#109

As mentioned in the comments, When we upgraded Airflow from 2.8.1 to 2.9.2, FivetranOperator in airflow-provider-fivetran-async package started giving issues abruptly.

We are using the FivetranOperator to trigger a Fivetran connector. The connector completes in 5-10 minutes, but the Airflow task does not finish. It remains in a deferred state until it times out and fails.

Airflow Version : 2.9.2
airflow-provider-fivetran-async==2.1.0
