Playground does not respect 'use node' directive

[DennisKraaijeveld]

Hi,

When defining agents inside definePlaygroundAPI that uses 'use node', deployment to the hosted Playground version fails.

✘ [ERROR] Could not resolve "node:crypto"

    convex/lib/email.helpers.ts:10:27:
      10 │ import { createHash } from "node:crypto";
         ╵                            ~~~~~~~~~~~~~

  The package "node:crypto" wasn't found on the file system but is built into node. Are you trying
  to bundle for node? You can use "platform: 'node'" to do that, which will remove this error.
✖ 
It looks like you are using Node APIs from a file without the "use node" directive.
Split out actions using Node.js APIs like this into a new file only containing actions that uses "use node" so these actions will run in a Node.js environment.
For more information see https://docs.convex.dev/functions/runtimes#nodejs-runtime

These errors won't happen when deploying the code to Convex itself.

Good call - not sure what the solution here is - maybe exporting a generateText function in the "use node" file and configuring the playground to use that one for certain agents? any other ideas?
