A method is being called on an object whose declaring type is a trait marked with the @internal tag. The trait is an implementation detail of the library and is not part of its public API. Methods originating from internal traits should not be called from outside the library because the trait may change or be removed in future versions.
Avoid calling methods that come from internal traits. Look for alternative public API methods that provide the same functionality:
namespace App {
- /**
- * @param \Vendor\InternalTrait $obj
- */
- function test(object $obj): void {
- $obj->traitMethod();
+ function test(\Vendor\PublicService $obj): void {
+ $obj->publicMethod();
}
}
