clerk-fastify-starter's Issues

Please include documentation on how the passed request should be structured, getAuth() is a black box

Missing clerk secret or API key

When trying this (without setting secret key as in example) nothing happen for first few tries.
https://github.com/clerkinc/clerk-fastify-starter/blob/main/src/authenticating-specific-routes.ts

but after that, it shows error

{
    "statusCode": 500,
    "error": "Internal Server Error",
    "message": "Missing Clerk Secret Key or API Key. Go to https://dashboard.clerk.com and get your key for your instance."
}

So I tried it like this, I overwrite the original clerkCLient

const clerkClient = createClerkClient({
  publishableKey: process.env.CLERK_PUBLISHABLE_KEY,
  secretKey: process.env.CLERK_SECRET_KEY,
})
const userClerkData = userId ? await clerkClient.users.getUser(userId) : null;

I see there's other sample here
https://github.com/clerkinc/clerk-fastify-starter/blob/main/src/using-runtime-keys.ts

but I want to use the first method link (where authenticate only on specific route)

but still same error shows up.
