double middleware execuation

[makbari]

Is there an existing issue for this?

• I have searched the existing issues

Current behavior

exclude a path in setGlobalPrefix cause middleware to trigger twice.
now, calling /api/hello will trigger the LoggerMiddleware to call twice.

without exclude: ['/'], works as expected.

Minimum reproduction code

Steps to reproduce

Expected behavior

It should only call the logger middleware once

URL doesn't work (sandbox)

please re-open the page again and try to access the https://4wrsdk-3000.csb.app/api/hello in preview page.

My issue is not about that (#13318), but as I'm using a middleware, I can confirm that it's executed twice in my reproduction.

[micalevisk]

from what I've tested this bug exists since @nestjs/core 10.2 and probably older versions

Do you guys want to investigate it further? maybe you can start from packages/core/middleware/route-info-path-extractor.ts file

Let's track this here #11832
