Object is possibly 'undefined'

I'm getting a lot of errors for typescript in nuxt image. I am using nuxt v4 compatibility mode if that makes a difference

 ERROR(vue-tsc)  Object is possibly 'undefined'.

I’m hitting the same issue, and I believe it’s related to the latest release v3.13.0. It seems that there were changes in the types, which might be causing this problem. I found this Vue TypeScript Changes that mentions updates to TypeScript handling, but I’m still unsure how to resolve the issue.
