No CreatedBy when created by API

Discord Q&A strapi-questions
1

I am using Strapi V4, and I have created a middleware that allows returning the ‘createdBy’ field:

javascript
Copier le code


module.exports = (config, { strapi }) => {
  return async (ctx, next) => {
    if (!ctx.query.populate) {
      ctx.query.populate = ["createdBy"];
    }

    await next();
  };
};```
It works well; however, when I create an element via a POST request, the 'createdBy' value is set to 'null'.

You have to set the populateCreatorFields option to true in the schema of your content type

createdBy is a relationship to admin users only, it will not be set for users-permissions users.
