Bug report

Describe the bug

Before I met this problem, I added some entities and extended User, Product Entities. Not sure those changes are associated with this problem.

After I run medusa develop, I get:

❯ medusa develop

And then I tried to access backend multiple times with http request and also admin dashboard, all failed with: net::ERR_CONNECTION_REFUSED

Meanwhile, the admin dashboard is reachable, just cannot login.

Here are some screenshots:

Admin dashboard console log

Postman http request result

However, all migrations are working as expected.

System information

Medusa version (including plugins): 1.15.0 Node.js version: 16.20.2 Database: Local Postgres Operating system: MacOS M2 Browser (if relevant): Safari / Chrome

Steps to reproduce the behavior

1. Run command medusa develop

Expected behavior

Expect all http request working properly.

Code snippets

Here are some migrations that I executed, I hope it helps.

After all, it didn't add a new credential to the database...

This error seems like a plugin error? which is quite weird since I haven't do anything about plugin.

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! 🙏
