[5.8] Argument 1 passed to Illuminate\Database\Query\Builder::cleanBindings() must be of the type array, null given

• Laravel Version: 5.8.12
• PHP Version: 7.2.14
• Database Driver & Version: MySQL 5.7.20

Description:

Just this morning upgraded from 5.8.11 to 5.8.12 which completely broke my application on the wherePivot part.

Broken:

$variable = $user->books()->wherePivot('owner', true)->findOrFail($id);

Fixed:

$variable = $user->books()->wherePivot('owner', '=', true)->findOrFail($id);

Has this been done intentionally? I cannot find anything regarding this change inside the core update. My code has not changed since the upgrade from 5.8.11 -> 5.8.12

It seems to me like a unintentional change, because it's not regarding every other where statement where it's just assumed that '=' is the operator if no operator is specified. Could this possibly be related to the changes made to the where here: #28192

Lucky i am using withPivotValue() method which internally uses

$this->wherePivot($column, '=', $value)

@ankurk91 I fail to see how this is contributing to this core issue.

Hey, the original PR was reverted (04a547e) and was released in 5.8.13. This issue is now solved. An additional test has been submitted to prevent future issues. #28260

This issue has arisen again in Laravel Version 5.8.23

@mjhorninger What query causes this error for you?

So it's a nested set of models, and needs to be refactored desperately.
We can query all the way down through three layers of models, but when we try to access a convenience method on the bottom layer that retrieves a non-related model, it breaks.

The bottom query that fails is: Pair::whereIn('id', $groupOfPairIds)->get();

What's the last working Laravel version?

What's the result of dd($groupOfPairIds);?

dd($groupOfPairIds) gives an array -
[ 0 => 32 1 => 34, 2 => 36 3 => 38 ]
