It looks like you're passing an entire block, not just the image asset. Can you try doing

For some reason it seems to me that this is a problem of the updated react/next
Aug 24, 2022, 3:28 PM
Can you use optional chaining? It likely isn't defined yet if it's relying on an external call.
Aug 24, 2022, 3:31 PM
no, it's not about optional chaining, I'm sure. Its about library and React/Next. I'm not the only one with this problem
Aug 24, 2022, 3:37 PM
No, if you look at your data, your image field is actually an array of images, not an object. Dot notation won't work for accessing the asset.
Aug 24, 2022, 3:41 PM
You'll need to map through that array as well.
Aug 24, 2022, 3:41 PM
but I have 1 image and in tutorial it is working, lol
Aug 24, 2022, 3:44 PM
how can I loop?
Aug 24, 2022, 3:44 PM
You can map through an array.
Aug 24, 2022, 3:45 PM
I know, but how to do it with those images? I just don't get it. I'm trying, but nothing happens

will iterate through your array of images. Then you'll need to return an image component for each image.

I've even tried [0] before

I'd suggest rereading carefully through your code. You're not returning anything from your image map. This reproduction works for me:
      {products?.map(product => (
        <div key={product._id}>
          {product?.image?.map(image => (
            <img src={urlFor(image).url()} />

Oh, yeah. Thanks!
Aug 24, 2022, 5:08 PM
You are welcome! It's always a little thing like that.
Aug 24, 2022, 5:09 PM
I've just uploaded 1 more picture and I'm getting 2 arrays instead of 1.
Aug 24, 2022, 5:11 PM
even without that closure

If your client has a token, you're likely also getting the draft version of the document. It looks like you haven't published the changes in the Studio.
Aug 24, 2022, 5:13 PM
omg, you are right
Aug 24, 2022, 5:16 PM
thank you so much!!
Aug 24, 2022, 5:16 PM
You're very welcome 🙂
