Vercel builds errorring out due to Invalid Vercel URL.

Hi! Stuck during first deployment of my T3 app. It keeps saying the VERCEL_URL is invalid but looking at the env variables the VERCEL_URL is set and is set to https://**.vercel.app VERCEL_URL: z.string().url().optional(), VERCEL_URL: process.env.VERCEL_URL,

https://%2A%2A.vercel.app/ is not a valid URL (due to the *). You can remove .url() if you really want it to be that string.

It doesn't fix your issue but if you want to use optional() with environment variables : Empty string ("") is not the same as undefined or null, you can use this schema:

VERCEL_URL: z.string().url().optional().or(z.literal("")),

VERCEL_URL: z.string().url().optional().or(z.literal("")),
