[v4] strapi populate query error "entry must be an object"

Looking at the docs Populating for Query Engine API - Strapi Developer Docs

It seems like you should be able to do

let result = await strapi.entityService.findMany('api::article.article', {
      populate: {
        comment_id: {
          select: [
            "id",
            "comment",
            "status"
          ],
          where: {
            status: {
              $eq: eduStatus.ACTIVE
            }
          }
        }
      },
    });
