When i try to run the app and pipe the output to loggo, i get this. The panic happens not always, it's strange. Here is a stacktrace:

➜  hollywood-test git:(main) ✗ go run ./cmd/server | loggo stream
panic: interface conversion: interface {} is string, not map[string]interface {} [recovered]
        panic: interface conversion: interface {} is string, not map[string]interface {}
