uploadApi not uploading video file

I am trying to add videos with react-dropzone to submit a data model via user entry and I’m currently running into some issues.

Going through the docs, it seems like a video has to be uploaded before it can be used in the writeApi>

I have tried used the uploadApi to upload a both a .mov and mp4 file but have been getting 400 (image not specified) or 500 (internal sever error) errors.

Does anyone else have any thoughts on how to add videos to a data model via user form submission?

Example snippet of attempting to use the uploadApi.

Side Note:

I have also changed the content-type to ‘video/.mp4’ & ‘video/.mov’ and that doesn’t seem to work either

      const reader = new FileReader();
      reader.onload = () => resolve(reader.result);
      reader.onerror = (err) => reject(err);

const attemptUpload = async (file) => {
    try {
      return await fetch(
          method: 'POST',
          headers: {
            Authorization: `Bearer ${token}`,
            'Content-Type': 'multipart/form-data'
          body: file,
    } catch (err) {

Hi @ktran, Welcome to the Builder.io Forum!

Looks like using Upload API- videos, and pdfs giving an Internal Server Error. We will work on the fix and keep you posted!

Hello @garima, are there any updates on this?
