fetch not following redirects

quick question about the HTTP Actions: I'm getting some inconsistencies in how the Fetch API works, and I'm not sure if they're expected I have a shortlink, and if I fetch it, I would expect it to follow that redirect and then set req.url to the target URL. in Node, this happens how I expect. in Convex, I'm still getting the shortlink in req.url

const res = await fetch('https://example.com/shortlink');
const headers = res.headers;

console.log(res.url);

const res = await fetch('https://example.com/shortlink');
const headers = res.headers;

console.log(res.url);

is this intended behavior?

This is a known shortcoming, the Convex runtime doesn't implement redirects or some of the options of the fetch API yet. This is on the list, we'll let you know when it's in.

gotcha. thanks!

second this ^ we'd really like to redirect from http convex endpoints

You can redirect from Convex http endpoints today, syntax looks like

return Response.redirect("http://place-to-redirect/to");

return Response.redirect("http://place-to-redirect/to");

the request in this thread is about fetch() calls initiated in V8 actions not following redirects

I see, thank you

@jlengstorf by the way, the Convex runtime already follows redirects in fetch (and always has). but it doesn't set Response.url or Response.redirected correctly. I'm working on those now and it should be working today or tomorrow

thanks Lee! I knew it was following, which was great, but for my weird use case the specific thing I needed was the Response.url

this should be working now. let us know if you run into any more problems
