Is there no more .logger function on the builder in 3.0? Is there an alternative or should it be done manually somehow? I didn’t see this being mentioned in the migration logs, a bit lost here.

That's correct. The rationale is that logs are not very structured and you can use interceptors to get the same information in a more structured way

With this context it sounds reasonable, and I understand the rationale. Since this was such a deliberate decision, imo it’s super important to be on the migration guide, for sure. Thanks for the clarification!
