Process completed with exit code 1.

Invalid assignment: the right-hand side has type `never` and cannot produce a value. >Cannot assign a `never` type value here An expression with type `never` is guaranteed to exit, throw, or loop indefinitely. Help: This assignment is unreachable because the right-hand side never completes. Remove the assignment or refactor the preceding code.

Invalid `clone` operation on non-cloneable type `(WP_Post|array<array-key, mixed>|null)&array<int|string, mixed>&WP_Post&null`. >This expression is not an object The `clone` operator can only be used on objects. This will cause a fatal `Error`. Help: Remove the `clone` operator or ensure the expression evaluates to a cloneable object instance.

Impossible condition: variable `frmstylescontroller::$post_type` (type `string`) will always be `null`. >This condition always evaluates to false Variable `frmstylescontroller::$post_type` (type `string`) is already known to be `null`, so asserting it's not `null` is impossible. Help: The condition checking if `frmstylescontroller::$post_type` is not `null` will always be false. Review the variable's state or condition.
