@matthewlilley Probably the Next.js compiler.

You can close this issue here and the discussion can continue on the one your created for graph-client. I am certain we all will find a solution.

@ronag Some people bundle their Node.js application code into a single JavaScript file that contains everything for easier/faster deployment. I guess in this case people would have to transpile the undici with babel or even better omit the non-“Node.js 14” code by configuring webpack to instead load a “noop” module.
