Description
Describe the bug
When a prop is destructured in their export declaration, it would ask for a default value because of the complex binding, and if a user uses a primitive type value (which someone did, asked a question in SO, the reason this issue is raised), it just errors out
with TypeError: Cannot read properties of undefined (reading 'reassigned')
which I assume is caused by an attempt to reassign an immutable variable.
Note that this does only happen during build time, and the code would work perfectly fine on dev mode
I know creating readable error traces depends on issues found, and I think there can be a better error message that would tell the person about it, or maybe prevent them from destructuring a prop.
