Description

In the new version BatchEntityFetch stopped working adequately with some variation of composite keys, resolvable false, sharable

Steps to Reproduce

Use the schema I sent you in the mail
#959 (comment)

Run Query:

query TestidentificationReports {
  identificationReports(
    filter: {
      idIn: "123456789"
    }
    page: 1
    perPage: 1
    sort: ORDER_CREATED_AT
    sortDirection: DESC
  ) {
    items {
      event {
        documents {
          document {
            payeeAmount
          }
        }
      }
    }
  }
}

Expected Result

Working Query as in the old version of cosmo or apollo.

Actual Result

{
  "message": "expected at least one definition, found }",
  "extensions": {
    "code": "GRAPHQL_PARSE_FAILED"
  }
}

Also, the Query Plan does not always work, probably for the same reason
Sometimes subgraphs from cosmo receive broken JSONs

By doing a variation Query I achieved a working plan and saw there this

router@0.107.1 and down OK

I.e., this MR broke download: #1092
