got caught off guard by vercels data cache... we call the hypersub smart contract to get a users remaining time via serverless function the calls are made with viem/alchemy, which uses fetch under the hood I guess vercel started caching fetch requests recently? this led to subscriptions not being recognized in our app ๐

If you run into this issue, you can add this route segment config to disable fetch caching within your route https://nextjs.org/docs/app/api-reference/file-conventions/route-segment-config#fetchcache

This has been the case since next 13 was released, but they recently announced theyโre rolling back the automated caching behavior because everyone hates it lol

i believe viem has a way to set cache headers for http requests. but not sure if vercel would respect that.

Vercel moment lol Literally one of the most bloodsucking companies in the modern industry trying to get everyone hooked on SSR, which sucks up a ton of cash and is useless in 9 out of 10 cases, while not offering anything that cheap VPS with open-source control panels can't offer

You should return a cache-control header from your lambda to prevent this or do a post or add a ?tm= cache bust parameter of unixtime.

@polluterofminds and I know this too well with some projects we were working on; drove us absolutely mad until we eventually figured it out ๐ซ

LOL, been rekt by the same thing 3 months ago. You have to explicitly set the request's to not cache.
