GraphQL Mutation not working

[fh-rranjan]

On our hosted medplum server (version 3.0.2-c34ad9a1).
I tried to run mutation query PatientUpdate on Medplum graphQL playground, It's sending null value in response and data is not getting updated on medplum dashboard.
Query:

mutation PatientUpdate {
  PatientUpdate(
    id: "b92cfbe5-0a18-42db-bba3-0ceaca8e81ef"
    res: {
      resourceType: "Patient",
      name: [{given: "Homer"}]
    }
  ) {
    id
    name {
      given
    }
  }
}

Response:

{
  "data": {
    "PatientUpdate": {
      "id": null,
      "name": null
    }
  }
}

Hi

Can anyone help me out in this?
Do you required some more details to resolve this?
Please let me know if any.
Please try to resolve this as soon as possible. I'm stuck here.

Thanks

Hi @fh-rranjan -

There are two immediate issues:

1. An update operation requires id to be duplicated in the body (sorry, I know that's weird, but that's the FHIR GraphQL spec)
2. You're passing Patient.name.given as a string, when it should be an array of strings.
   • name: [{given: "Homer"}] should be name: [{given: ["Homer"]}]

There is a separate issue, which is that the error is not correctly returned for mutations. We're working on a fix now. Thank you for reporting.
