Fixed in #57578. This will be released at the next provider release

[ddione84]

Hi am also getting the same error dispite upgrading fab provide to the latest 3.0.2

Hi am also getting the same error dispite upgrading fab provide to the latest 3.0.2

Did you also upgrade airflow to latest? Both are needed.

[ddione84]

yes I have upgrated to Airflow 3.1.3

[potiuk]

Did you also upgrade to latest FAB provider? It's been explaied above.

[potiuk]

You need to upgrade both in case you have not realized. In case you have any problems - please open a new issue with detailed description of your deployment and issue you had. Thanks in advance for making maintainers life easier by doing it @ddione84

[gavrik]

Yes, The FAB provider should be updated to the new version.
