Does this affect all operations?

Not sure if I get the question right. It is an error during compile time. Actually, I assume in practice the code will work.

Im new to StackBlitz but i gave it a try. I hope it works for you.

-> https://stackblitz.com/edit/webpack-webpack-js-org-maeyov?file=package.json

I used

1. npm exec --yes @hey-api/[email protected]
2. webpack

to get the error.

@fnep this will be fixed in the next release, but I suspect it won't solve all your issues. I tried with your example and after fixing this issue, I was getting a weird Webpack error failing to build the services.gen.ts file if I understand it correctly. I believe this might be something to do with the Webpack config itself, but open a new issue if you find out more and think something needs to be fixed in this package.

Just updated to 0.48.0 and for me, this solved the issue entirely. Thank you! 🙂

Would you be able to create a minimal reproducible example on StackBlitz?

I had the same issue. I think it's related to the typescript version you use. With typescript 4 I get the same error. With typescript ^5.00 it works for me.

I'm on typescript 5.3.3 in my project, and the StackBlitz example above is on 5.5.2.
