[Bug]: Generated named routes do not filter out undefined values from query params

[antonmoiseev]

What's not working?

Functions generated for named routes, do not filter out query string params with undefined values. They do so for path params , but not for query.

How do we reproduce the bug?

Assuming you have a Redwood app with "home" route. Pass any args to the generated routes.home() function that have undefined value:

// returns following string: "/a=1&b=undefined"
routes.home({ a: 1, b: undefined })

What's your environment? (If it applies)

Hey @antonmoiseev! Just confirmed this. I agree it's not exactly what one would expect. To navigate with the real undefined and to get the string "undefined" in the params.

Do you want to implement a fix for this one too? No pressure of course we can add it to our internal list if you don't have the time. Your contributions are awesome and always appreciated!

[antonmoiseev]

I'd be happy to! Spending more time on a Redwood project now, glad to contribute back to the extent of my capacity.

[Josh-Walker-GM]

Perfect if you need anything just let me know!
