Zone filters cause crash?

I am using Postman to explore the Cloudflare API. I have set the Authorization header to a Bearer token as shown in the examples. The token itself was created in the API panel, where it has read access to all zones. However, when I call, I get a 500 error.

    "success": false,
    "errors": [
            "code": 500,
            "message": "Server error"
    "messages": [],
    "result": null

Where is this documented? All of the examples with CURL specify query string arguments and all the gems I can find also seem to use the query string.

Sorry, my bad. Yes, your query should be correct.

Thanks. So why the crash then?

Most likely the same as Got a 500 response when purging cache with API

Any ETA on a fix?

Nothing has been announced.
