How to Fix Replicate Run Error Readablestream in Nextjs

If you try to use Replicate’s Node.js client follow by model pages, like this :

const output = await replicate.run("black-forest-labs/flux-schnell", { input }); 
console.log(output[0]);

you will get result :

ReadableStream { locked: false, state: 'readable', supportsBYOB: false }.

You need change to :

const [output] = await replicate.run(model, { input });
console.log(output.url());
