Hi,

When I save a file locally and Next.js performs a fast refresh, I sometimes get an undefined cookie even though I know the cookie is stored. When I perform a full refresh of the page in the browser, I get the cookie again.

It is important to note that I am getting the cookie in a layout when it appears as undefined.

All I am doing is performing this action:

const sessionId = cookies().get(lucia.sessionCookieName)?.value ?? null;

Is there something that I am missing on when it comes to cookies and fast refresh?

Thanks.
