Failed to resolve field query*

We are running Squidex version 7.18.0.0 on a k8s cluster. We have a dedicated Mongo7DB as we running this at DigitalOcean. We made a backup of our Cloud and succesfully imported it. We are now getting errors “Failed to resolve field on several queries. For example:
{“logLevel”:“Error”,“message”:“Failed to resolve field queryCarbonProjectsContentsWithTotal.”,“field”:“queryCarbonProjectsContentsWithTotal”,“timestamp”:“2026-01-06T13:27:28Z”,“app”:{“name”:“Squidex”,“version”:“7.18.0.0”,”

what is causing this and how can I resolve this?
