Hello @sunnyson, could you help me? I followed your instructions and despite showing a 422 error, the post is still published. Here is the code:
async beforeCreate(params, data) {
const post = await strapi.query('post').find({ id: params.id });
if (
post[0].published_at &&
(!post[0].subcategories.length || !post[0].categories.length)
) {
throw new Error('Category or subcategory is missing');
}
}
