CodePudding user response：

The fields are probably not supported by faker. Try something like this:

DB::table('categories')->insert([
            'name' => $faker->name,
            ...
            ...
            ...
        ]);

CodePudding user response：

i have deleted all the related files in factories, and model and re created it again and i also upgrade my PHP Version from 8.0.9 to 8.1.1 and i have change in composer.json file "fakerphp/faker": "^1.9.1"(php 8.0.9)

"require-dev": 
{"fakerphp/faker": "^1.20",

after doing this its fix automatically.
