🐛 BUG: @astrojs/netlify/functions doesn't support base64 encoded responses

[tony-sull]

What version of astro are you using?

1.0.0-beta.44

Are you using an SSR adapter? If so, which one?

Netlify

What package manager are you using?

pnpm

What operating system are you using?

Mac

Describe the Bug

Netlify Functions requires that the function's body is a string. To support certain use cases like returning a Buffer for an image, the response needs to be base64 encoded and include the isBase64Encoded flag

@astrojs/netlify/functions currently only supports text responses and doesn't have a way to use the isBase64Encoded flag

Possible Solutions

This is a tricky one since API endpoints only return a standard Response object. For Netlify, it could potentially check if response.body is a string, and if not assume it needs to be base64 encoded

Another option would be adding a custom header in the endpoint Response, but that could be a little weird since it really is adapter specific
