@balub commented on GitHub (Jun 13, 2024):

Hey @lvreninfo, could you try removing the double quotes enclosing the values for the environment variables in the .env file? similar to how the values for the VITE_BASE_URL are.
Adding the relevant URL to the WHITELISTED_ORIGINS env variable should be enough to prevent CORS issues so could you trying remove the double quotes everywhere and trying again?
