I fixed this issue by simply updating discord environment variables like shown below in .env file:

DISCORD_CLIENT_ID="sample"
DISCORD_CLIENT_SECRET="sample"

[sahilrajput03]

Also, you can fix it via making discord env values optional in env.js file:

    DISCORD_CLIENT_ID: z.string().optional(),
    DISCORD_CLIENT_SECRET: z.string().optional(),

I believe there is a section in the "First Steps" part of create-t3-app's documentation that addresses this issue.
Look under "Authentication": https://create.t3.gg/en/usage/first-steps
