@necessary129 getting the following error after upgrading synapse from v1.44.0 to 1.47.1. any idea why?

Traceback (most recent call last):
  File "synapse_worker", line 17, in <module>
    main()
  File "synapse_worker", line 11, in main
    app = config.worker_app
AttributeError: 'HomeServerConfig' object has no attribute 'worker_app'

Found the issue. Synapse changed how configuration variables are referenced through a series of changes: matrix-org/synapse#10985.

Fxied it by changing config.worker_app to config.worker.worker_app in line number 9.
