Map not working as expected

[nir-r]

The below map and input wont work as expected.
Also, try, try.dev and rambam servers react diffrently

1. fume map
2. fume input
3. fume error (from rambam => baseURL: 'http://ec2-3-124-79-139.eu-central-1.compute.amazonaws.com:52773/csp/healthshare/rambam/fhir/r4',)
4. console error

AFAIK, this issue was resolved by fixing the mapping code. Closing this issue, please re-open with more info if necessary
