Description

Using an enum as an "ID" when using find() and its derivatives is supported because the where logic converts the instance via enum_value().

In Builder::findOrFail() the $id variable is passed to ModelNotFoundException::setModel() where it becomes part of the exception message. But nothing makes sure the value of the ID can be used in a string.

In 11.x up to 12.18 the line looks like:

if (is_null($result)) {
    throw (new ModelNotFoundException)->setModel(
        get_class($this->model), $id
    );
}

In setModel() method:

if (count($this->ids) > 0) {
    $this->message .= ' '.implode(', ', $this->ids);
}

I notice the same behavior would occur if the count of fetched Models doesn't match the ID count.

Steps To Reproduce

1. create table foo(id int) (no data)
2. artisan make:model Foo
3. Make new class enum FooNum: int { case One = 1; }
4. Query Foo::findOrFail(FooNum::One)

Expected error (approximately):
No query results for model [Foo] 1

Got instead (approximately):
PHP Fatal error: Uncaught Error: Object of class FooNum could not be converted to string
