Been following the buildspace AI avatar generator project and loving it so far!

I did come across an issue when creating the React app. In the bufferToBase64 function:

const bufferToBase64 = (buffer) => {
    let arr = new Uint8Array(buffer);
    const base64 = btoa(
        arr.reduce((data, byte) => data + String.fromCharCode(byte), '')
    )
    return `data:image/png;base64,${base64}`;
};

I had an issue with btoa not being defined:

error - ReferenceError: btoa is not defined

I did an npm install --save buffer and added import { btoa } from "buffer"; to pages/api/generate.js which fixed my issue. Not sure if anyone else had the same issue?

I was following the guidance here, and the suggestion was to replace the unique subject identifier before sending the prompt to the Hugging Face API.

I was slightly confused about what this was for. For example if we do the following:

'a photo of abraza'.replace(/raza/gi, 'abraza')

that would give:

'a photo of ababraza'

and if 'abraza' wasn't provided in the initial prompt, 'abraza' wouldn't be present in the prompt before POSTing to the API. Is this correct?
