Using NextJs and try to create a session

The code is:

TypeScript
export async function createSessionClient(userId: string, sessionSecret: string): Promise<AppwriteClient> {
  console.log("Creating session client...");
  console.log("User ID:", userId);
  console.log("Session Secret:", sessionSecret);
  
  const client = new Client()
    .setEndpoint(process.env.NEXT_PUBLIC_APPWRITE_ENDPOINT as string)
    .setProject(process.env.NEXT_PUBLIC_APPWRITE_PROJECT as string)

    //create session
    const account = new Account(client);

    const result = await account.createSession(userId, sessionSecret);

    console.log("Session created:", result);

Error:

TypeScript
AppwriteException: Invalid `secret` param: Value must be a valid string and at least 1 chars and no longer than 256 chars

  45 |     console.log("Session created:", result);

}```


```json
 "dependencies": {
    "appwrite": "^17.0.0",
    "next": "15.1.2",
    "next-auth": "^4.24.11",
    "node-appwrite": "^15.0.0",
    "react": "18.3.1",
  },
TL;DR
Developers are experiencing an error stating "Invalid `secret' param" when creating a session in a NextJS app using Appwrite. The error is due to the session secret being either null, too short, or too long. Make sure the secret provided is a valid string between 1 and 256 characters.
