Help uploading rst docs

[konsumer]

Pardon me if this is not be the place to ask, but I am having trouble ingesting the godot docs (rst text format.)

Here is my code:

import { glob } from 'glob'
import r from 'r2r-js'

const { R2RClient } = r

const baseUrl = 'http://localhost:8000';
const client = new R2RClient(baseUrl)

for (const f of await glob('data/**/*.rst')) {
  const tags = f.split('/')
  tags.shift()
  tags.unshift('godot')
  const fname = tags.pop()
  tags.push(fname.split('.')[0])
  try {
    const uploadResponse = await client.uploadAndProcessFile(tags.join('/'), f, {tags})
    console.log('Upload response:', uploadResponse)
  } catch(e) {
    console.error(e.response.data.detail)
  }
}

I get a ton of error Invalid file type. Allowed types are: txt, json, html, pdf.

How do I tell it that it's a txt document?
