Error building search index when updating

[Benjamien]

Hi,

I have a recurring problem when updating.
This error is present for a while now, but I can get past it by editing the common_site_config.json file and setting the maintenance_mode to 0.
But I would like to get this fixed to my updates run smooth again.

Thanks.

My environment:
Ubuntu 18.04 LTS
Frappe v13.15.0
Erpnext v13.15.2

The error:

Syntax error in query:
select route
from tabBlog Category
where tabBlog Category.1 = 1.0

                     order by `tabBlog Category`.`modified` DESC
