Component not being populated in strange behavior

[Norbz]

Hi

I've encountered an issue where one of our component isn't being populated (there's a missing "cover" media field) no matter what depth we specify. The said component is in a dynamic zone.

The strange thing is that the bug occurs on a singleType that is almost the duplication of another collectionType that is working perfectly.

Here is the definition of the faulty singleType

{
  "kind": "singleType",
  "collectionName": "homepages",
  "info": {
    "singularName": "homepage",
    "pluralName": "homepages",
    "displayName": "🏠 Homepage",
    "description": ""
  },
  "options": {
    "draftAndPublish": false
  },
  "pluginOptions": {
    "url-alias": {
      "enabled": false
    }
  },
  "attributes": {
    "definition": {
      "type": "string",
      "required": true
    },
    "featuredlink": {
      "type": "component",
      "repeatable": false,
      "component": "texts.button"
    },
    "hero": {
      "type": "media",
      "multiple": false,
      "required": true,
      "allowedTypes": [
        "images"
      ]
    },
    "title": {
      "type": "string",
      "required": true
    },
    "content": {
      "type": "dynamiczone",
      "components": [
        "data.custom-editorial-list",
        "data.custom-project-list",
        "data.editorial-list",
        "data.event-list",
        ...
      ]
    }
  }
}

The component data.custom-project-list is missing it's cover field. I've switched the homepage into a collectionType without any success. In any case does the populate param include this : [content][populate][items][populate][cover]=true

The "working" collectionType has the same dynamic zone with the same components, same name (content), just different fields around... I've forked the plugin and traced everything, I cannot understand the differences between my two content-types in terms of behavior from the plugin...

Does anyone has any issue similar to this ?

Hello @Norbz. We had similar issues within our dynamic zone component. Following patch fixed it.
