Feast ui cannot parse url path

[snowron]

Expected Behavior

One of example cases:
When user navigate localhost:8888/p/order_count_project/feature-view/user_3_and_7_days_order_count should see related feature-view page

Current Behavior

One of example cases:
When user navigate localhost:8888/p/order_count_project/feature-view/user_3_and_7_days_order_count see "Internal Server Error"

Steps to reproduce

install feast 0.34.1
run feast ui
navigate homepage localhost:8888
navigate any page (entities or feature-view or data sources doesn't matter)
you will see the page you clicked at browser search bar like http://localhost:8888/p/order_count_project/data-source
then refresh or copy url open in new tab
you will see internal server error

Specifications

• Version: 0.34.1
• Platform: macos
• Subsystem:

Possible Solution

ui_server.py file updated recently. commit changes resource finder library and then it returns PosixPath.
We should convert to str and add little "/" to "@app.api_route("/p/{path_name:path}", methods=["GET"])" function

Faced the same problem.

Everything works fine until you refresh a page.
Any page reload triggers the same python error (PosixPath and string concat) which results in Internal Server Error.
