Review comment (bug):
Let's not do type casting on the fly, this can lead to server panic if the cast fails.
Instead use
```go
casted, ok := jsonData.(map[string] interface {})
```
And check the ok value to be true

We might be able to use predefined function for extracting the type. This way we can remove `const ObjTypeMask = 0b11110000` as well.
