Relation with withTrashed() break after version 5.7.22

[martingautier]

• Laravel Version: 5.7.22
• PHP Version: 7.1.9

Description:

I have a simple relation :
public function user() { return $this->belongsTo(User::class, 'user_id')->withTrashed(); }

It works on laravel version 5.7.22, but from 5.7.23 I have this error :

"Property [relationClauses] does not exist on the Eloquent builder instance."

Thanks for your feedback.

Can you post the stack trace please? This could be related to #27281, but I don't see the use of relationClauses in core, so this might be a—previously silently—failing property access in your own code.

I'm sorry but I made a mistake. This error comes from another package who overrides my relations (fico7489/laravel-eloquent-join).
This package no longer works with version 5.7.23.
For informations, it performs the following code:
$this->getQuery()->relationClauses[] = [$method => $parameters];
