GitHub API - Comment on Gist returns 404

Question

After following the documentation on GitHub's API, I got stuck on submitting a comment for a gist, the following code always returns 404, and the same call made in Postman too.

My JavaScript code as follows:

const config = {
        method: 'POST',
        headers: {
            'Authorization': credentials.authorizationHeader,
            'Content-Type': 'application/vnd.github.v3.text+json'
        },
        body: { "body": JSON.stringify(comment) } 
    };

    fetch(`https://api.github.com/gists/${gistId}/comments/`, config)
        .then(res => {
            if (res.ok) {
                dispatch(getGistDetails(gistId, credentials));

                dispatch({ type: SUBMIT_COMMENT_SUCCESS });
            } else {
                ToastAndroid.show('An error ocurred, please try again.', ToastAndroid.SHORT);
                console.log(res);
                dispatch({ type: SUBMIT_COMMENT_FAIL });
            }
        })
        .catch(err => console.log(err));

Credentials I'm getting via OAuth:

accessToken: "redacted"
authorizationHeader:"bearer redacted"
clientID:"redacted"
idToken:null
scopes:"gist"
type:"bearer"

I tried changing the authorizationHeader to token <oauth_token, but still no success.

Thanks in advance.

404 is a `Not Found` error code. Most likely the `url` you're using points to an non-existing `gist` — Zilvinas, Sep 06 '17 at 21:08
The `gist` exists. As per the API's documentation, more often than not a `404` indicates a `403`, but my credentials are (supposedly) correct. — jacques mouette, Sep 06 '17 at 21:10
For reference, this is the `gist` I'm trying to comment on: `https://gist.github.com/desktp/8e376d6cd8d671e14c735d051eff7140` — jacques mouette, Sep 06 '17 at 21:12
looks like you have some hidden UTF characters in the query above... — Zilvinas, Sep 06 '17 at 21:13

Looks like you have some non standard characters in your GIST ID that are not even visible and I can't even get your link to work ( or is it private? )

That's really strange, I copied and pasted directly from the address bar. Still, in my code, the gist `id` is coming from the API. I first request the gist details, which occurs without a problem, but then the comment fails. Let me try the address here again: `https://gist.github.com/desktp/8e376d6cd8d671e14c735d051eff7140` – jacques mouette Sep 06 '17 at 21:28
Nope, same thing again – Zilvinas Sep 06 '17 at 21:29

Turns out I was overcomplicating, as getting a gist's details through the API also nets you a comments_url field with the correct url, so no need to splice strings, falling into the very strange issue mentioned by @Zilvinas below. Also, a minor adjustment in the body to

const body = { body: comment }

const config = {
    method: 'POST',
    headers: {
        'Authorization': credentials.authorizationHeader,
        'Content-Type': 'application/vnd.github.v3.text+json'
    },
    body: JSON.stringify(body)
};

fixed the subsequent Problems parsing JSON error I got.
