Github domain(githubHost) is `undefined` in Vercel

[UnschooledGamer]

I'm hosting an api docs at vercel and noticed that go to source code link has Github Domain(githubHost) is displayed as undefined, the url it gave: https://undefined/parasop/poru/blob/main/src/Player/Connection.ts#L61.
Whereas it works completely fine locally.

While searching in the source code of this repo, I found this.

Do I need to provide the githubHost in the docusaurus config?
I did not provide it as the docusaurus docs said:

The hostname of your server. Useful if you are using GitHub Enterprise. You don't need this if you are not using the docusaurus deploy command.

Thanks.

@milesj Please have a eye here.

[milesj]

I'm not entirely sure what the correct fix is here.

[BartaG512]

As I have found Typedoc has its own logic, handling other hosts than github.
url handling

That logic probably modifies and returns undefined, I just fixed it by providing githubHost explicitly.
