after upgrade from 4.1.3 to 4.2.1 whoosh backend error

[woec]

Hi,
after I upgraded mayan from 4.1.3 to 4.2.1, search does not work anymore (whoosh backend).
When refresh of the search index is initiated, the errors listed in the attached log file are issued.
django search backend still works.

Error message starts with:
ERROR/ForkPoolWorker-3] Task mayan.apps.dynamic_search.tasks.task_index_search_model[28d0d40c-b04a-4177-b9dc-b65ac026b055] raised unexpected: DynamicSearchException("
Unexpected error calling `index_search_model` with keyword arguments {'range_string': '51-74', 'search_model': <SearchModel: Cabinet>}.")

How to solve this?
woec

Addendum: replacing the contents of .../apps/dynamic_search/ by the files from 4.1 tree of gitlab, searching by use of whoosh works again!
So, I suspect there is something wrong with the code of version 4.2 ...

Installation environment: debian testing, direct installation

Hi @woec,
thank you so much for your addendum, that solved the problem for me, too!
You saved my day!

I’m facing the same issue on docker
In 4.2.8 whoosh does not complete the reindex.
In the addendum could you explain exactly what you did?
Thanks
