Endpoint "media/metadata/create" fails

[NiciusB]

It seems like it actually makes a successful request, but it fails to parse the result.

Here is some extremely hacky code if anyone needs it. It's bad, but it will not throw

const crossFetch = require('cross-fetch')

function customTwitterPostForAltText (twitterClient, body) {
  const resource = 'media/metadata/create'
  const baseHeaders = {
    'Content-Type': 'application/json',
    Accept: 'application/json'
  }

  const { requestData, headers } = twitterClient._makeRequest(
    'POST',
    resource,
    null // don't sign JSON bodies; only parameters
  )

  const postHeaders = Object.assign({}, baseHeaders, headers)
  body = JSON.stringify(body)

  return crossFetch(requestData.url, {
    method: 'POST',
    headers: postHeaders,
    body
  })
    .then(res => {
      if (res.status !== 200) throw new Error('[customTwitterPostForAltText] ' + JSON.stringify(res))
    })
}

Hi @NiciusB, sorry for the delay. I'm a bit confused, did you solve this issue with the snippet you posted above?

I did, but it's not ideal since it's ignoring the result of the request. If the request succeeds we have no access to the response, and if twitter returns an error, the actual error message will be lost.

Basically what I wanted to do was to upload an image with a caption.

// Upload image
const b64content = '' // Base64-encoded image
const mediaUploadData = await twUploadClient.post('media/upload', { media_data: b64content })

// Set alt text for image
const altTextString = 'Animated image of a cat failing a jump'
await customTwitterPostForAltText(twUploadClient, { media_id: mediaUploadData.media_id_string, alt_text: { text: altTextString } })

// Tweet
const tweetData = await twClient.post('statuses/update', {
  status: 'Check out my accesible image',
  media_ids: [mediaUploadData.media_id_string]
})

Hey @NiciusB do you mind creating a PR that would fix this for our users? We'd really appreciate it, thanks!
