Wagtail django.db.utils.OperationalError: (1463, "Non-grouping field 'numchild' is used in HAVING clause")

I'm working on a Django project and I've encountered an issue that I'm unable to resolve. When I try to run my application, I get the following error:

django.db.utils.OperationalError: (1463, "Non-grouping field 'numchild' is used in HAVING clause")

I'm not sure what's causing this error. I'm not explicitly using a HAVING clause in my queries, and 'numchild' is a field that's managed by Django's** Wagtail** module, not something I've added myself.

I'm using the following packages:

wagtail>=5.0 mysqlclient==2.2.4

Every things working fine locally using sqlite.

I tried to downgrade my mysqlclient version from 2.2.4 to 2. Without sucess. I would like to have the result as sqlite.
