PHP Error: Call to a member function bindTo() on null about serializable-closure HOT 5 CLOSED

Hi,
I'm currently facing this issue right now. After some debug, it turns out that this only occurs while working with Tinker.
It appears that the closure's body isn't saved correctly.

I'm using this library to store closures as models attributes, using a "Closure" cast.

No problem encountered handling those SerializableClosure during database seeding, we can clearly see this function section inside the serialized object :
"function";s:60:"function ($arg) { return $arg; }"

But when I manipulate an instance of this model inside Tinker :

>>> $m = MyModel::first();
=> App\Models\MyModel {...}
>>> $m->closure = function (int $a, string $b) { return "$a: $b"; };
<warning>PHP Warning:  file_get_contents(eval()'d code): Failed to open stream: No such file or directory in /var/www/html/vendor/laravel/serializable-closure/src/Support/ReflectionClosure.php on line 805</warning>
=> Closure(int $a, string $b) {#4617 …2}
>>> $m->save();
=> true

the function field of the stored SerializableClosure is empty : "function";s:0:"";
, and cause the error message of this thread issue.

I've retried to update this model inside a test command, and everything works fine.

As mentionned by suhaboncukcu, it is probably due to the way Psy Shell terminal treat or cache these fields, so it is probably a missing feature rather than a bug.

@suhaboncukcu The code example you gave, does not contain any code that would cause that issue. Are you able to clone this serialisable project locally, and try to reproduce your issue in test?

I will re-open the issue once you answer.

Sorry for the late reply. After further investigation, I found out the reason. For the future searchers; if you're using job_batches, loading a corrupted row on your batch table can fill your logs up with this error due to horizon requests for instance.

What I find strange is that whenever I run the above example on tinker , I'm ending up in the same state. It basically adds a row which can't be unserialized correctly. This could also just about my terminal or zsh so I'm not sure if psy/psysh is causing this problem or not. In any case, package -indeed- doesn't seem to have any problems in regular usage.

Hi,
I'm experiencing this error, too, although the only way I was able to replicate it was via tinker as @suhaboncukcu mentioned.

bash-5.0$ php artisan tinker

it is weird to me that there is no closer trace
