The Query is to find all leads filtered by the userid which is stored in loadedby [String]

query LeadMany($filter: FilterFindManyLeadInput) {
  leadMany(filter: $filter) {
    name
    loadedby
}
}

The Filter variables

{
  "filter": {
    "loadedby": ["123"]
  }
}

Which returns the data correctly

{
  "data": {
    "leadMany": [
      {
        "name": "A",
        "loadedby": [
          "123",
          "789"
        ],

But when I want to sort it by the second index in the loadedby array it doesn't return. So the filter is only checking with the first index

{
  "filter": {
    "loadedby": ["789"]
  }
}

{
  "data": {
    "leadMany": []
}}
