Hi all
Trying to get the MAIN branch from https://github.com/ui5-community/generator-ui5-project with the following code:

import { Octokit } from "@octokit/rest";
import { HttpProxyAgent } from "http-proxy-agent";
import { retry } from "@octokit/plugin-retry";

const ghOrg = "ui5-community",
    repoName = "generator-ui5-project",
    branch = "main";

const proxy = process.env.http_proxy;
const agent: HttpProxyAgent | unknown = proxy !== undefined ? new HttpProxyAgent(proxy) : null;

const RetryOctokit = Octokit.plugin(retry);
const octokit = new RetryOctokit({
    log: {
        debug: console.log,
        info: console.log,
        warn: console.log,
        error: console.log,
    },
    userAgent: "generator-easy-ui5",
    request: {
        
        agent: agent
    }
});

octokit.repos.getBranch({
    owner: ghOrg,
    repo: repoName,
    branch,
}).then(console.log)
    .catch(e => {
        console.error("#################### ERROR ####################");
    });

it shows:

  branch: 'main'
}
