Related entries are not being returned

Craft 3.1.17.2 CraftQL 1.3.1

I am using entriesConnection to query a given entry by its id and then use relatedEntries to get reverse related entries from a given section. This has worked in the past, but right now this query is returning an empty object for my relatedEntries part.

Here's the full query:

query getScript($id:[Int]) {
  entriesConnection(id:$id) {
    edges {
      node {
        ...on Scripts {
          id
          title
          postDate
          expirationDate
          diagnosis
          client { id title url }
          veterinarian { id title url }
          sites { id title url }
          replaces { id title url }
          drugsMatrix {
            ...on DrugsMatrixFormulaItem {
              __typename
              drug { id title url }
              unitOfMeasure_FieldData { selected { label } }
              outOfStock
              replacedBy { id title url }
            }
          }
        }
      }
      orders: relatedEntries(section:orders) {
        edges {
          node {
            ...on Orders {
              id
              title
            }
          }
        }
      }
    }
  }
}

Everything returns fine except orders just returns the following:

"orders": {
  "edges": []
}

But I know for a fact this entry is related to 12 different Order entries.
