Error in 2.4.2 / 2.4.4 : no such entity

Hello ! Since 4 days my 2.4.2 and 2.4.4 test envs are experiencing strange issues and I’m looking for more infos.

The main error is my checkout page showing errors like “no such entity CustomerId=342” when the customer is logged in. If I m looking at the DB, this user exists.

Something weird is that this error happened on 2 envs that do not have same code versions and the error seems having appeared at the same time !

Their only common aspect is the same mariadb instance on azure…

Is it possible that a lack of db performance or a module problem (seems that the vertex module could be involved) could lead to this ?

Thanks for your infos !
