Error: Image with src "/placeholder.svg" is missing required "width" property

Question

I am getting this problem when I link this page code with my main page. I'm stuck here, I tried everywhere to solve it.
enter image description here it shows this error.

<Image 
alt="Donghua Image"                                                   
className="rounded-lg object-cover w-full aspect-[6/3] group-hover:opacity-50 transition-opacity"                                                   
height={300}                                                   
src="/placeholder.svg"                                                   
width={400}                                            
/>
