UnhandledSchemeError: Reading from "node:zlib" is not handled by plugins (Unhandled scheme)

Question

Anyone can help resolve this error? I have tried resolving using polyfills and every other solution i could find online and think by myself but i still keep getting the issues

Answer 1

Option A

I also encountered this issue when using node-fetch: ^3.0.0 but downgrading to node-fetch: ^2.0.0 resolved it for me.

Option B

You need to declare these as externals. https://webpack.js.org/configuration/externals/

Webpack 4

  target: node

Webpack 5

  externalsPresets: { node: true },

I also use webpack-node-externals but this might not apply in your case.
