Custom HTTPAuthentication: how to use getUser's callback with a null value for error

[jahjedtieson]

HTTPAuthentication.getUser has a callback parameter with the signature callback: (error: Error, user?: webdav.IUser) => void. In typescript, it's not possible to call this method without supplying an Error, which in turn seems to signal that the request is not authenticated.

Should this signature be updated to callback: (error?: Error | null, user?: webdav.IUser) => void?

And if not, how do we call the callback to indicate that the request is authenticated?

Note that I'm able to work around this with the comment // @ts-ignore: ts(2345) before calling the callback with a null Error ... but this shouldn't be necessary.

getUser(ctx, callback) {
const onError = (error) => {
callback(error, null);
};
// if error => {
onError(Errors_1.Errors.MissingAuthorisationHeader);
return;
}
// if no error => callback(null, mapUser);
};
