Runtime errors with axios after upgrading in Bun

[baljimaurya]

Hey everyone,

I’m running into a weird issue in Bun and could use some advice. I recently upgraded axios from 0.21.4 to 1.11.0 to fix a vulnerability. The build works fine, but when I run the app I get this error:

Uncaught TypeError: Cannot read properties of undefined (reading 'call') in webpack_require

Some things I’ve tried:

• Importing axios as both import axios from "axios" and import axios from "axios/dist/node/axios.cjs"
• Removing any aliases in bunfig.toml
• Clearing the Bun cache and reinstalling dependencies

Sometimes it works after a full rebuild, but not consistently.

Has anyone else run into this with Bun? What’s the best way to handle dependencies that ship both ESM and CJS builds? I want to make upgrades stable without breaking runtime.

Thanks for any tips!
