i have the same issue, very frustrating in the last 2 days, very very wasting time & energy.
This solved the problem for me: https://docs.medusajs.com/troubleshooting/admin-webpack-build-types
Hey, thanks for the report! Since v2 brought a lot of architectural and API changes on the backend, we will be closing this ticket since it no longer applies to our new setup, or the issue has already been fixed. If you are still facing issues with v1, please open a new ticket and we will address it as soon as possible. Thanks! 🙏
