TS error: params incorrectly

[evshank]

The Generate Dynamic Embed Images guide in the Base documentation contains an incorrect TypeScript typing for params in Next.js App Router examples.

Currently, the documentation types params as a Promise<{ username: string }> and accesses it using:

const { username } = await params;

However, in Next.js App Router:

• params is always a synchronous object
• is not a Promise
• its type is { username: string }

Using the code in the current example results in an error:
TS2741: Property ‘username’ is missing in type ‘Promise<{ username: string; }>’ but required in type '{ username: string; }'

After the correction, the code compiles without errors.

This issue has been addressed in PR#1108
The PR updates all affected examples to the correct typing and removes await params.
