Magic link invalid url and baseURL issue

When I try to generate a magic link, I get this error:

After digging into the stack trace, I noticed that ctx.context.baseURL inside the internal package is coming through as undefined. (screenshot attached) I haven’t manually set a baseURL, but when I try to configure one explicitly, everything breaks—the API endpoint no longer works. Instead of the API handler responding, Svelte serves a 404 page (screenshots 2 and 3). My guess is that the issue lies in Svelte’s routing/handler setup. Setting the baseURL seems to cause Svelte’s route handling to intercept the request, leading to the 404 page instead of correctly hitting the API.

Solution:

Fixed it: Issue was because it was behind a proxy it recieved http instead of https
