Image upload fails using datauri from browser

@aleclarson @junhoyeo getting a Upload image failed error. I have the following base64 image that will render on the UI using an <img src="..." /> tag

If I do something like:

const base64 = ... // image string above
const data = base64.split(',')[1];
const buf = Buffer.from(data, 'base64');

await client.publish({
    text: 'test',
    attachment: {
        image: { type: 'image/png', data: buf },
    },
});

verbose error:

[UPLOAD_IMAGE] Uploading 2,292b as 1690005367354...
[UPLOAD_IMAGE] FAILED {
  debug_info: {
    retriable: false,
    type: 'ProcessingFailedError',
    message: 'Request processing failed'
  }
}

Using v1.5.4.

I can also confirm that if I remove the imagefield, the post is published so not a credential issue.

Related issue #111

@aleclarson it's from clipboard as a blob, then I convert it to a base64 datauri string using:

const blobToBase64 = (blob: Blob): Promise<string> => {
  const reader = new FileReader();
  reader.readAsDataURL(blob);
  return new Promise((resolve) => {
    reader.onloadend = () => {
      resolve(reader.result as string);
    };
  });
};

It renders on the UI so I know it's working, but based on the comments in #111 it looks like png's are not working?

Yeah looks like converting to a jpg blob works but the file quality is not good
