You need to use faker like this:

$this->faker->sentence()

I put the code in and got this error

class ListingFactory extends Factory
{
    /**
     * Define the model's default state.
     *
     * @return array<string, mixed>
     */
    public function definition()
    {
        return [
            'title' => $this-&gt;faker-&gt; sentence(),
            // 'tags' => 'Laravel, API, Backend',
            // 'company' => $this->faker()->company(),
            // 'location' => $this->faker()->city(),
            // 'email' => $this->faker()->companyemail(),
            // 'website' => $this->faker()->url(),
            // 'description' => $this->faker()->paragraph(5),
        ];
    }
}

ParseError

syntax error, unexpected token "&"

Commented out several lines just trying to limit until I get some code working

@rkellogg12 I see in your code that you have a -> (the html attribute) and not the arrow -> that result in the error. If you change it I suspect that it will work.

Ps. I have updated your posts to have clear codeblocks.
