bug: npm run build error

Describe the Bug

I installed the adapter, added it to my svelte.config.js and initialized firebase with firebase init.

When I run npm run build I get the following error:

> Error: Required "hosting[].rewrites" field not found for matched hosting configuration. Specify your Cloud Function with rewrite rule matching "source":"**"

If I update the hosting object to include rewrites, do you have an example of what that function in <functionName> should look like in functions/index.js?

"hosting": {
        "public": "public",
        "rewrites": [
            {
                "source": "**",
                "function": "<functionName>"
            }
        ],
        "ignore": [
            "firebase.json",
            "**/.*",
            "**/node_modules/**"
        ]
    }

I updated it to

"rewrites": [
            {
                "source": "**",
                "function": "ssrServer"
            }
        ],

and now I’m getting the function in the terminal
