Latest version of Gdevelop (5.6.256+) breaks url query param support

Is there an existing issue for this?

Describe the bug

My companies game relies on using query params to pass data to the game. In version 5.6.257 (editor full version: 5.6.257-675a58ed1f9936250cd6cd71a644e4f33944a0f4, core version: 5.6.257-0) when adding a query param to a games url it will now open the listing directory

In all previous versions of gdevelop this worked with no issue

Steps to reproduce

1. Open a game with web preview
2. Add a param to the url ie: http://urip:2929/?i=123
3. It will now open the listing directory instead of opening the game like normal
4. http://urip:2929/ will still open the game like normal but yeah it seems like it is treating query params as a route now?

Hi @alexleybourne can you share screenshots of what you're seeing? the error message you're having?

Note: I can have query params work correctly without the trailing / so http://urip:2929?i=123 instead of http://urip:2929/?i=123 but let me know exactly the error you have

[alexleybourne]

The browsers auto add the trailing / I tried to keep removing it. I noticed it wasn't an issue when I downgraded though. Gdevelop wouldn't throw an error it would just open the games file directory. The fix you merged looks good. Is there any easy way for me to test it? Thanks 🙏
