Passing args in URL with `experimental.basePath` causes the page to constantly being reloaded.

Bug report

Describe the bug

We are using next: “^9.4.1” in a project with experimental.basePath and when working with the project on development and we have params on URL the page constantly reloads making impossible to work on dev mode.

To Reproduce

Steps to reproduce the behavior, please provide code snippets or a repository:

I generated a simple repo & code-sandbox to show the problem.

• Contains a basepath set to myPath
• Only contains a simple index page with a link to add params to the URL,

When you load the visit the project with params: Live Sandbox and click on the link, o directly go to the URL with params on the URL

The page loads correctly, but after a second it starts to reload from time to time.

If no params in the URL or experimental.basePath set, it works like as expected.

Expected behavior

I would like to work with experimental.basePath without unexpected page reloads.

Additional context

Obviously this is an experimental feature based on this PR but we will need sooner than later in our projects.

Thanks in advance 🙏

I’m having the same issue without setting assetPrefix. I’m trying to narrow down the problem.

Hi, it looks like you are setting both assetPrefix and basePath to the same path here. You only need to set basePath in this case since /_next requests will automatically be prefixed with the basePath

Yeah, but in our real case, we are routing this next.js application through Traefik through the same base_path, and we need both the app and the assets to be served inside the same base_path. That’s why we need to change both.
