I previously tried using the workers R2 Runtime error and got the same error too. Any tips on how to debug this?

I tried putting my source code together here in case anyone wants to give it a spin Workers : https://gist.github.com/ivanleomk/d31d49ce7412dc958bec353a273e0925

On the front end, I am splicing files using a simple .splice function.

export const createChunks = (
  file: File,
  chunkSize = 15 * 1024 * 1024 /* cSize should be byte 1024*1 = 1KB */
) => {
  let offset = 0;
  const originalFileExtension = getFileExtension(file);
  console.log(`Identified Extension as ${originalFileExtension}`);
  const chunks = [];
  while (offset < file.size) {
    const chunkEnd = Math.min(file.size, offset + chunkSize);
    const truncatedBlob = file.slice(offset, chunkEnd);
    const truncatedFile = new File(
      [truncatedBlob],
      `audio-${offset}-${chunkEnd}.${originalFileExtension}`,
      {
        type: file.type,
      }
    );
    chunks.push(truncatedFile);
    offset += chunkSize;
  }
  return chunks;
};
