Not possible to add metadata to medias

[smndhm]

I'm trying to add metadata to an uploaded media but I get the following error :

{
    "request": "/1.1/media/metadata/create.json",
    "error": "Invalid json payload."
  }

Here is the Twitter doc : https://dev.twitter.com/rest/reference/post/media/metadata/create.html

My guess is that the request header and/or body needs to be changed in this case.

I get a 400 error when I try to add metadata. Here's what my request and error look like:

data = await readFile();
media = await client.post("media/upload", { media: data });
alt_text = "foobar";
client.post("media/metadata/create", {
    media_id: media.media_id_string,
    alt_text: {
        text: alt_text
    },
});

400 error response

I tried the adjustment mentioned earlier and it didn't work for me. All of the reference links are dead now, so here's the current one: https://developer.twitter.com/en/docs/twitter-api/v1/media/upload-media/api-reference/post-media-metadata-create

Alright well I moved on to twitter-lite and it works: https://github.com/draftbit/twitter-lite/blob/master/test/twitter.test.js#L219
