`{"error":{"root_cause":[{"type":"illegal_argument_exception","reason":"Failed to parse value [1] as only [true] or [false] are allowed."}],"type":"illegal_argument_exception","reason":"Failed to parse value [1] as only [true] or [false] are allowed."},"status":400}`

I get this error when i access [http://localhost:9200/\_nodes/transport?pretty=1](http://localhost:9200/_nodes/transport?pretty=1)

So it seems like i did some settings wrong but i am not sure were to look

can you share a bit more about your setup? What version are you running on? Does the same happen when you run `GET _nodes`. Can you run the request with this parameter and paste the full response

```auto
GET _nodes/transport?error_trace=true

```

thanks!

The problem here is the `pretty=1`. That is no longer accepted syntax as we have removed the use of anything but `true` and `false` to represent `true` and `false`. This problem will go away if you change `pretty=1` to `pretty=true`.
