After reading this topic https://forum.strapi.io/t/cant-get-createdby-from-api/15687/2
I was able to add the information to the content-type.
If someone have a better way of doing this feel free to comment.
async findOne(ctx){
const { id } = ctx.params;
const data = await strapi.db.query('api::wiki.wiki').findOne({
where: {
url_slug_full: id.replaceAll('%252F','/').replaceAll('%2F','/'),
},
populate: ['createdBy', 'updatedBy'],
});
const sanitizedEntity = await this.sanitizeOutput(data, ctx);
sanitizedEntity.createdBy = {
id: data.createdBy.id,
email: data.createdBy.email
};
sanitizedEntity.updatedBy = {
id: data.updatedBy.id,
email: data.updatedBy.email
};
return this.transformResponse(sanitizedEntity);
}
