octokit.js: Unexpected end of JSON input

I’m pretty sure I’m doing something wrong here, but I’ve exhausted what it is.

const octokit = require('@octokit/rest')({
    debug: true,
    host: 'github.<company domain>.com',
    pathPrefix: '/api/v3'
});

octokit.authenticate({
    type: 'token',
    token: '<personal access token with all scopes'
});

octokit.orgs.get({org: '<valid org>'}, (error, result) => {
    console.log(error);
});

Output:

SyntaxError: Unexpected end of JSON input
