I have checked this issue in CKAN version 2.11. This issue is reproduced.
The below error is occurred because engine object is not initialized and it is None.

File "/usr/lib/ckan/default/src/ckan/ckanext/tracking/middleware.py", line 42, in track_request
with cast(sa.engine.Engine, engine).begin() as conn:
AttributeError: 'NoneType' object has no attribute 'begin'

#8448 PR will fix this error in logs.

This error cause the server process .crash (and restart). If it occour during loading resources or harvesting all fail.
