Please describe.**\r\n\r\nIn one of my project, there are multiple feature stores in one application. However, the ui server doesn't seem to support it.\r\n\r\nI can show the issue with a simplified example. I have two local feature stores with project names `store_1` and `store_2`. At the root folder of `store_1`, I run\r\n```\r\nfeast ui --port 8890 --root_path /something\r\n```\r\nwhen I use my browser to hit `http://localhost:8890/`, the server logs:\r\n```\r\n\"GET /something/registry HTTP/1.1\" 404 Not Found\r\n```\r\nIt is due to the [path of registry](https://github.com/feast-dev/feast/blob/v0.33.1/sdk/python/feast/ui_server.py#L69) doesn't include the `root_path`.\r\n\r\nAfter I change the path of registry to\r\n```python\r\n@app.get(f\"{root_path}/registry\")\r\n``` \r\nand run two ui servers for the two feature stores by\r\n```\r\n# at the root folder of store_1\r\nfeast ui --port 8890 --root_path /something\r\n\r\n# at the root folder of store_2\r\nfeast ui --port 8891 --root_path /something-else\r\n```\r\nthen use the browser to hit `localhost:8890`, the log of the server of `store_1` shows\r\n```\r\n\"GET /something-else/registry HTTP/1.1\" 404 Not Found\r\n```\r\nIt is because the configuration of `store_2` overwrites `projects-list.json` at [here](https://github.com/feast-dev/feast/blob/v0.33.1/sdk/python/feast/ui_server.py#L56)\r\n\r\n**Describe the solution you'd like**\r\n\r\nI would suggest to make the following changes\r\n1. include the `root_path` into the [path of registry](https://github.com/feast-dev/feast/blob/v0.33.1/sdk/python/feast/ui_server.py#L69),\r\n2.  use an individual `projects-list.json` (maybe change it to `projects-list-\u003cproject_id\u003e.json` ) for each ui server.","author":{"url":"https://github.com/heavenmarshal","@type":"Person","name":"heavenmarshal"},"datePublished":"2023-08-14T21:57:35.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":3},"url":"https://github.com/3728/feast/issues/3728"}
