Hi @boreens - are you using a typesafe ORM like Prisma by chance?

[boreens]

Yes, drizzle-orm is used

I'm not sure if this is very helpful for you too @boreens, but I was facing the same and I switched from using Zod to straight-up types as events and I don't see this error anymore. I think Zod adds a few additional layers of abstractions so with many events I was constantly seeing this error.
