Redirect to external URL from server function 2

To avoid necroing the original thread, Tanner has suggested to return a 302 and redirect 'as normal' https://discord.com/channels/719702312431386674/1299757633758035998/1299766886631870474 But this in fact does not work, and instead you get

{"message":"Request failed with status 302","body":{"result":{"$undefined":""},"context":{}}}

{"message":"Request failed with status 302","body":{"result":{"$undefined":""},"context":{}}}

so idk how I am supposed to handle this now EDIT trying t call the server fn from the FE with useServerFn results in

ServerFn Response: 500
 - Payload: {"code":"ERR_HTTP_HEADERS_SENT"}

ServerFn Response: 500
 - Payload: {"code":"ERR_HTTP_HEADERS_SENT"}

but like, duh, ofc headers were sent thats how you redirect

OK update: The answer is to use sendRedirect from vinxi despite that being explicitly advised against

Maybe the veriage here needs to change? https://tanstack.com/router/latest/docs/framework/react/start/server-functions#redirects Its mentioned that sendRedirect shouldn't be used of 'soft redirects', whilst you are doing an external/hard redirect.

Server Functions | TanStack Router React Docs

What are Server Functions? Server functions allow you to specify logic that can be invoked anywhere (even the client), but run only on the server. In fact, they are not so different from an API route,...

I think that the distinction itself is poorly named, one is simulated navigation and performed clientside, and the other is a redirection. hard/soft suggest proper/improper semantics Even knowing how this works I fell for the naming

wise-white•10mo ago

Suggestions here? Just internal/external redirection then?

modern-tealOP•10mo ago

basically, yes, imo at least also I just noticed, even with sendRedirect I get

DefaultCatchBoundary Error: Error: {"message":"Request failed with status 302","body":{"result":{"$undefined":""},"context":{}}}

DefaultCatchBoundary Error: Error: {"message":"Request failed with status 302","body":{"result":{"$undefined":""},"context":{}}}

which is a big issue, as I'm using the vinxi session to perform auth and the session does not seal for an error

This may have to do with the bug where server functions at the moment aren't accounting for users returning a Response.

I am not returning a response, I'm returning null as I already encountered that issue lol

LOL

wise-white•10mo ago

Tanner is working on it

modern-tealOP•10mo ago

0 is also no good

modern-tealOP•10mo ago

it's the sendRedirect itself thats fucky

wise-white•10mo ago

Confirming by looking at the source of h3, sendRedirect is meant to be returned 'as-is'. We'll only be able to confirm this behaviour here once the server function bugs get squashed

modern-tealOP•10mo ago

Must have not thought that one through as theres nothing you can return from sendRedirect regardless

modern-tealOP•10mo ago

redirections in general are not allowed to have bodies so this does not surprise me

modern-tealOP•10mo ago

Huh, I have a serverFn that is basically just returning the session, and it seemingly is fully able to do so

modern-tealOP•10mo ago

but the body arrives as undefined OK the issue is that I'm calling session.update more than a single time which creates 2 Set-Cookie headers, corrupting my data
