Description of Error

After upgrading @clerk/nextjs from version 6.9.15 to 6.10.1, server actions started failing on await currentUser() with the following error:

 ⨯ Error: Clerk: Unable to decrypt request data, this usually means the encryption key is invalid. Ensure the encryption key is properly set. For more information, see: https://clerk.com/docs/references/nextjs/clerk-middleware#dynamic-keys. (code=encryption_key_invalid)

}

Implementation-specific Details

• Instead of using NEXT_PUBLIC_CLERK_PUBLISHABLE_KEY, I have an environment variable called CLERK_PUBLISHABLE_KEY that I pass to <ClerkProvider> and clerkMiddleware at runtime (this is so I can use the same docker image with both test and live keys).
• This error did not happen when using the default environment variables instead of passing them at runtime as described above.

Replication Instructions

1. Add your clerk keys to .env.local. Note: the publishable key should be called CLERK_PUBLISHABLE_KEY not NEXT_PUBLIC_CLERK_PUBLISHABLE_KEY.

CLERK_PUBLISHABLE_KEY=pk_***
CLERK_SECRET_KEY=sk_***

2. Generate a CLERK_ENCRYPTION_KEY and add it to .env.local:

echo CLERK_ENCRYPTION_KEY=$(openssl rand -base64 32) >> .env.local

3. Create a production build (error not seen in development mode)

npm run build

4. Run and try to load the page

npm run start

Replication Instructions (with Docker)

1. Add your clerk keys to .env.local. Note: the publishable key should be called CLERK_PUBLISHABLE_KEY not NEXT_PUBLIC_CLERK_PUBLISHABLE_KEY.

CLERK_PUBLISHABLE_KEY=pk_***
CLERK_SECRET_KEY=sk_***

2. Generate a CLERK_ENCRYPTION_KEY and add it to .env.local:

echo CLERK_ENCRYPTION_KEY=$(openssl rand -base64 32) >> .env.local

3. Build the docker image

docker build -t app .

4. Run the docker container

docker run --rm -p 3000:3000 --env-file .env.local app

Expected Error

When I attempt to load the page I get an error in the server component render. It errors out on the line:

const user = await currentUser();

With the following error message (on the server):

 ⨯ Error: Clerk: Unable to decrypt request data, this usually means the encryption key is invalid. Ensure the encryption key is properly set. For more information, see: https://clerk.com/docs/references/nextjs/clerk-middleware#dynamic-keys. (code=encryption_key_invalid)
