Help with a relationship error

[BigBoss]

For the past few days, I've been receiving an error message in the logs. Do you have any ideas, please?

For error 1, try deleting the relationship from the interface. Go to the "users" entity, then fields, and delete the line corresponding to "cases12."

It happens in espoCRM, that on deleting relationships from the Admin GUI, there will be kept information to that field in the entityDefs json file, which you then have to delete from that file manually.
Also in the database there might be tables for that field, which you also should delete manually.

If you do not delete in the json file, espoCRM will try on every rebuild to create the fields again, in the GUI on recreation it will tell, that such relationship already exists, even you had deleted it before.

So, if you have to delete a relationship, always afterwards clean everything, which had been created from that relationship.

You can also execute a hard rebuild. But on any operation, keep a working backup of custom folders and database.
