Bug coverImage with WordPress and Next.js

[acoruble]

Hello !

I had a bug with WordPress and Next.js :
"Server Error
TypeError: Cannot read property 'node' of null"
It's because I don't have a coverImage for all my posts.
So, I change this line :
" coverImage={node.featuredImage.node}"
By this line :
" coverImage={node.featuredImage?.node}"
In this file : components/more-stories.js
And :
I change this line :
" coverImage={heroPost.featuredImage.node}"
By this line :
" coverImage={heroPost.featuredImage?.node}"
In this file : pages/index.js
And :
I change this line :
" coverImage={post.featuredImage.node}"
By this line :
" coverImage={post.featuredImage?.node}"
In this file : pages/posts/[slug].js

Maybe I make a mistake because I just begin to work with Next.js but If someone have the same problem :)

And if someone have tips, i listen you !

Have a nice day !
