Having trouble trying to override fetch

[aletorrado]

Question

Hi, I've been doing some extremely simple tests just trying to override the fetch option, using the native fetch utility, and without adding any additional logic at the moment, but I'm getting errors this way.

This is the code I'm trying:

const innertube = await Innertube.create({
	fetch: async (requestInfo, init)=>{
		// This references to native fetch
		return fetch(requestInfo, init)
	},
});

And this is the error I'm getting:

TypeError: Failed to parse URL from [object Request]

    input: '[object Request]',
    code: 'ERR_INVALID_URL'
  }
}

I've tried with Node v20.5.1 and v18.17.1 with the same results.

Am I doing something wrong? Thanks!

It doesn't work with the node-fetch library either. Debugging shows that youtubei.js sends an Undici Request object to the provided fetch function instead of the original Url , whereas the provided fetch function requires either the original Url or its own library's Request object.

I'm not using node-fetch. It's the native fetch, as stated in the comments.

I know you are not using node-fetch. I'm saying it doesn't work with the native fetch. And it doesn't work with node-fetch either. And then I explain why it doesn't work in either case.

Try this:

import { Innertube, UniversalCache, Platform } from 'youtubei.js';

(async () => {
  const innertube = await Innertube.create({
    cache: new UniversalCache(true),
    fetch: async  (input, init) => {
      const url = typeof input === 'string'
        ? new URL(input)
        : input instanceof URL
          ? input
          : new URL(input.url);

      const request = new Request(
        url,
        input instanceof Platform.shim.Request? input : undefined
      );
      
      return fetch(request, init);
    }
  });
  
  const info = await innertube.getBasicInfo('zxLu32BizZg');
  console.log(info);
})();
