framework: Sql error when Model::where()->first()

Hi,

• Laravel Version: 5.6.20
• PHP Version: 7.2
• Database Driver & Version: mysql Ver 14.14 Distrib 5.7.22, for Linux (x86_64) using EditLine wrapper

Description:

Migration :

Schema::create('google_places', function (Blueprint $table) {
            $table->bigIncrements('id');
            $table->string('place_id');
});

Here is the code : GooglePlace::where('place_id', $place_id)->first();

Error produced by Eloquent Model :

SQLSTATE[HY000]: General error:  (SQL: select * from `google_places` where `place_id` = ChIJ_bzdbKTazRIR4-0ippvrlZo limit 1)

I have tested the sql statement on mysql cli and added quotes around the place_id:

select * from `google_places` where `place_id` = 'ChIJ_bzdbKTazRIR4-0ippvrlZo' limit 1

and the query works. How i can add quotes with an Eloquent Model?

Thanks for reply.
