Hi Medplum team. I’m running into an issue uploading

MedicationAdministration

resources within a FHIR Bundle. Every attempt to upload results in this error:

{
  "resourceType": "OperationOutcome",
  "issue": [
    {
      "severity": "error",
      "code": "invalid",
      "details": {
        "text": "reference.reference?.startsWith is not a function"
      }
    }
  ]
}

I’ve tried various modifications to the resource (e.g., changing medication references, removing encounter, using

occurrenceDateTime

), but the error persists. Consequently, no

MedicationAdministration

entries appear at https://app.medplum.com/MedicationAdministration. Other resources like

Patient

,

Condition

, and

Observation

upload and display with no issues. Any ideas on what could be causing this? I’d appreciate any help! Thanks!

@alex_empallo do you have an example bundle that you could share?

@rahul1 Hi, thanks for your message. Okay, I have attached one to this message. The

Patient

resource here is fine, but both of the

MedicationAdministration

resources yield the error from my previous message. I'm kind of working with dummy files for now, hence the

???

values for certain "unimportant" fields.

And just to confirm, this MedicationAdministration works correctly when not used in a batch?

Hi @rahul1, thanks for your response. The issue was indeed with the medication reference. I updated the

MedicationAdministration

resource to use

medicationReference

and moved the medication details into a

"contained"

key/resource. I also used

effectiveDateTime

to track DTM and removed the invalid encounter property. The upload is now working correctly, really appreciate your help!
