Question: difference between any and object without properties?

In the protocol definitions, I have seen occurrences of both type: "any" and type: "object" without any properties list.

What’s the difference? Is it that any can be anything including primitives (effectively any JSON value) but object is limited to only structures with properties (effectively only JSON objects)?

In that case, does an object without properties list represent a type whose properties are unknown/dynamic?

In the typescript definitions, I noticed that most params of type object without properties are represented with the Headers interface, which is basically {[key: string]: string}. This would confirm my guess here. However, some are still translated into TS’s any (e.g. PausedEvent.data), which is why I’m asking here.

@joffrey-bion, you’re reading it right – “type”: “any” implies any type at all, including primitive types such as boolean/numer/string, while “type”: “object” implies a JSON object (i.e. a dictionary with string keys and values of “any” type).

Ah I see, I had missed the usage in js_protocol.pdl. I have asked internally for clarification on this.
