I'm trying to install a node using the HTTP API: [https://nodered.org/docs/api/admin/methods/post/nodes/](https://nodered.org/docs/api/admin/methods/post/nodes/)  
I tried with several HTTP clients, like Postman but I'm getting the following error:

And if I try to use Java API I get the same HTTP 400 error:

> java.io.IOException: Server returned HTTP response code: 400 for URL: [http://localhost:1880/nodes](http://localhost:1880/nodes)

HTTP 400 indicates that there is a problem with the request itself but I can't see it, it seems to be the same as the example from the web page.

Any ideas? Thanks!
