Params are not reactive when { showDefaults: false } is set and during standard link navigation

[Jahoda]

Describe the bug

When I use { showDefaults: false }, arrive at a URL without search parameters, and then navigate using a standard HTML link (e.g., <a href="?pageNum=2">2</a>), the value in params.pageNum is not updated.

• When the search parameter is preset on page load, it works.
• When the search parameters are changed by updating params.pageNum, it works.

Version: 4.0.0-next.0

Thank you for your help.

Can support this bug report in that I just got tripped up by the same thing on the same version

This is a workaround, maybe:

const params = queryParameters({
	pageNum: ssp.number(Number(page.url.searchParams.get('pageNum'))),
},
{ showDefaults: false }
);

@Jahoda The above workaround does not work.
If you visit a page with no pageNum params then you paginate it's not reactive.
