renderToStream is not a function on react@canary

[robahtou]

Using "resend": "3.2.0" with the canary version of react to work through upgrading our apps to use useActionState`.

Within our actions we call out to resend. But once we did the package updates we started seeing this error:

TypeError: renderToStream is not a function
        at eval (webpack-internal:///(action-browser)/./node_modules/.pnpm/@[email protected]/node_modules/@react-email/render/dist/index.mjs:137:38)

Seeing the same error.

There is some further discussion here on the react-email repo: resend/react-email#1383 (comment)

I've been able to get this particular error to go away by:

• forking react-email and merging chore(render): Use renderToPipeableStream instead of renderToStaticNodeStream react-email#1443
• updating the render package to use the same v19 react/react-dom beta as nextjs 14.3.0
• forking resend and replacing the render package with the forked one
• using this version of resend in my app

Similar process for updating react-email/tailwind too (merging #1383)

However, its still not fully working, particularly the tailwind part so I'm stuck.

If anyone is still having this error:

I updated my resend package to latest version and it worked 👍
