Cause

• We send over the image base64 string to the backend, and the base64 string is too large to be sent over the network.

Solution

1. We can send the image url instead of the base64 string.

Changes

• Update the frontend to send the image url instead of the base64 string.
• Update the API to send the image url instead of the base64 string.
• Update the backend to handle the image url instead of the base64 string.
  • Download the image from the url.
  • Convert the image to base64 string.
