Maybe you are using <Img> component.

When you are using Img, have to set width and height value.

What do you mean? I'm not using "Img" component. only nextjs "Image"

I mean Image tag.

I have no problems building locally. the Image component is not a problem I think.

If you use html tag img, you don't need to set width, height value

I'm not using html tag img in my project.

But If you are using Next Image tag, you have to set width and height value.

when html img: <img src ="skkej" alt= " " />

when Next Image: <Image src="ksjef" width="400" height="300" alt="skjef" />

like above.

I have width and height on all Image components. These sort of problems would appear in the local build, which is working fine. I suddenly can't build to Vercel, that's the problem.

Did you run npm run build on local?

yes. zero warnings or errors. I can see in Deployments for my project that the last working build was actually "redeployed" in vercel dashboard. is it possible that is the problem?

It's completely broken. I can't even redeploy the latest successful deployment. What I've tried:
1. made sure the Node versions match in Vercel and locally,
2. running pnpm run build locally (it works) before pushing to Vercel,
* redeploying the latest successful deployment.

From what I remember the latest successful deployment that was a redeployment that I did after changing NEXT_PUBLIC_URL env variable from .vercel.app to my domain.

Full build logs text file from Vercel

I texted the Vercel support but if someone could look into it that would be great. i'm currently unable to built at all to production.
