[BUG]: Node transition failing after file upload

[Michael-N-M]

Description After a user uploads a file using choice skill, the chatbot does not transition to the next node. When testing this in the studio interface using the emulator, the studio UI goes blank after file upload.

To Reproduce Steps to reproduce the behavior:

1. Create a choice skill which returns either BOTPRESS.FILE_UPLOAD or BOTPRESS.IMAGE_UPLOAD
2. Link it to some nodes
3. Chat with the bot and upload a file
4. No transition after file upload

Expected behavior A clear and concise description of what you expected to happen.

• Botpress Version [e.g. 12.10.0]
• NodeJS [e.g. 12.13]

@vamsi2449 @Johna5821 your uploaded file is located in event.payload.url, so you can use it to send it via formData for example:

  let data = new FormData()
  data.append('proof_image', fs.createReadStream(event.payload.url))
  let config = {
    method: 'post',
    maxBodyLength: Infinity,
    url: '<url>',
    headers: {
      ...data.getHeaders()
    },
    data: data
  }
  const resp = (await axios.request(config)).data
