Help : not-supported:Cockpit is not compatible with the software on the system.

ubuntu 22.04
cockpit 300.1

This is my code for test cockpit.http.request

cockpit.http({
            "address": "",
            "port": 8080,
        }).request({ path: "/apps/catalog", method: "GET" }).then((response) => {
            console.log("response:" + response);
        }).catch((error) => {
            console.log(error);
        });

This is the resust:
Object { problem: "not-supported", message: "Cockpit is not compatible with the software on the system.", toString: toString() }

This is not a valid way to call .request(), see docs. You need to either specify body: "" or call .input() first. But it's easier to do this:

cockpit.http({ port: 8080 }).get("/apps/catalog")...

Still, this shouldn't cause a not-supported error, but just hang. So something else is wrong. Where/how exactly do you run this code?

I am customizing and developing a plugin for Cockpit, using create react app, which runs in React. Now that I have added body: '', it can run normally, but there is still something I don't understand. The interface I call through the request method is an API interface, and I need to handle different logic based on the status codes returned by the API, such as 200, 400, 404, and 500. However, it is how I should obtain the data returned by the API. It seems that I only obtained the data without the status code, But I tried using request. response ((status, headers)=>{...}), and here it seems that the body。

        cockpit.http({
            "address": "websoft9",
            "port": 8080,
        }).request({ path: “/apps/catalog”, method: "GET", body: "" }).then((response) => {
            console.log("status:" + response.status);
            console.log("body:" + response.body);
        }).catch((error) => {
             console.log(error);
        });

When the returned status code is 400, it is caught by the catch。 @martinpitt

Right, you'll get the .then() part for successful requests, and the .catch() part for failures like 4xx or 5xx. In that case error.status is the status code like 404:

>> cockpit.http({port: 8000}).request({ body: "", path: "/notexisting", method: "GET"}).catch(e => console.error(e))
Object { status: 404, reason: "File not found", message: "File not found", problem: null }

or alternatively if it's not a HTTP but a connection error:

>> cockpit.http({port: 8001}).request({ body: "", path: "/", method: "GET"}).catch(e => console.error(e))
Object { problem: "not-found", message: "not-found", toString: toString() }
