Good to know is that this did not happen on 19.8.0 so the issue has been re-introduced in 19.9.0. I say re-introduced because it was reported on < 19.15.0 versions as well #16137

Possibly related: nodejs/import-in-the-middle#188

Hey @gijsroge thanks for reporting this!

Just tried your repro locally on my machine but could not reproduce it – neither with npm nor with pnpm. Could you try nuking your node_modules folder and re-install your deps?

Thats so weird, just nuked node_modules and tried again and I do get the error. Im running node 23.7.0
