<Image src= { sessionData?.user.image} alt="user"   width={100}

An issue has been encountered:

There is a type error stating that 'string | null | undefined' cannot be assigned to type 'string | StaticImport'.
Type 'undefined' cannot be assigned to type 'string | StaticImport'.ts(2322)
image-component.d.ts(7, 5): The expected type is defined in the property 'src' which 
is declared here on type 'IntrinsicAttributes & Omit<DetailedHTMLProps<ImgHTMLAttributes<HTMLImageElement>,
HTMLImageElement>, "ref" | ... 5 more ... | "srcSet"> & { ...; } & RefAttributes<...>'

Is there a way to specify a type for it or should I leave it as is since no error is being displayed on the webpage?

Answer №1

sessionData?.user.image may potentially be undefined due to your use of optional chaining.

Setting undefined as the value for src doesn't seem logical.

Therefore, it's important to check for this condition and take a different approach.

What that alternative might be is not a coding issue. It could involve showing a different image, displaying no image at all, or handling an error scenario meticulously.

The solution will depend on your specific requirements. You may need to either add an if statement or utilize the nullish coalescing operator after the sessionData?.user.image expression with another value to address this situation. This decision-making process should be considered carefully (or delegated to someone else).
