    Use attribute casting in your model

        protected function casts(): array
{
    return [
        'options' => 'array',
    ];
}

    It seems like you might be trying to insert a json or array to doc_content field, so For that in your model you need to add Casts, it identifies special types of field or problem like you are facing might come. Casts is used for identifying special type of fields type, like json or array. So in your model you need to define

    Protected $casts = ['doc_content' => 'json'];

    And If you want to directly save array, then you can give,

    Protected $casts = ['doc_content' => 'array'];

    Also pls make sure you have made an json field while making table through migration.
