The issue with Wix Stores databases. Need help!

@loeix It will work for sure. But remember collections field is a reference. So, the result will be in Array. Like this

[
  {
    "_id": Collection ID,
    "name": Collection Name,
    "mainMedia": CollectionImage
  },
  { //Example
    "_id": "600655b5-63e1-e491-fedb-777a0bd6f0b8",
    "name": "Sale",
    "mainMedia": "wix:image://v1/c22c23_527e6c6f3d944fb88c80907c2f754afb~mv2.jpg/file.jpg#originWidth=2000&originHeight=2000"
  }
]

Result in console
