Question about request.accepts() function

[BolverBlitz]

Did the syntax change or is it a bug?

I´ve used request.accepts() in the past to respond to the clients wishes, ive updated hyperexpress from a about 2 year old version to the latest and this code now throws an error.
I looked through commits, my code works with 6.17.2 and breaks 6.17.3
There are 2 commits 8f9975d and 939293e where the this part was modifyed. @RatchetS2

Example Code:

const hyperExpress = require('hyper-express');

const app = new hyperExpress.Server();

app.get('/', (request, response) => {
    const acceptsHtml = request.accepts('html');
    response.send(`Accepts HTML: ${acceptsHtml}`);
});

app.listen(3000, () => {
    console.log('Server listening on port 3000');
});
