Current Limitation

Cannot insert items in the array using graphql. I've also asked a question on SO before. someone suggested me to post an issue

https://stackoverflow.com/questions/66552544/insert-items-into-array-using-graphql-parse-server

The following writes data into note field. I want to add items in the array.

mutation {
  updateParcel(input: { id: "B6aESEwWcA", fields: { notes: ["wow"]}}) {
    parcel {
      objectId
      notes {
        ... on Element {
          value
        }
      }
    }
  }
}

Alternatives / Workarounds

the only alternatives we have is to use Rest or SDK

Start by reproducing the updateParcel GraphQL mutation shown in the issue and compare its array-field behavior with the REST or SDK alternatives. Trace the GraphQL update path for array fields; done means a mutation can add items to an existing notes array without replacing its current contents, with coverage for the demonstrated case.
