where is your route.ts file located

if you access /api/cookie, then your route.ts file should be in /api/cookie/route.ts

can you try it in postman first

or rest/curl

hit localhost:3000/api/cookie

try using fetch() instead of axios

just to check

no worries

can you try writing localhost:3000 instead of from .env

can you try writing localhost:3000 instead of from .env

can you try without localhost:3000

so just directly /api/cookie

which one is that
