Hl7.Fhir.ElementModel.StructuralTypeException: 'Type checking the data: Since type Encounter is not a primitive, it cannot have a value (at start)'

Having an issue with the following:

LABM_13=>2019-03-29

mapping at Encounter.period.start

But it's shows wrong text
Hl7.Fhir.ElementModel.StructuralTypeException: 'Type checking the data: Since type Encounter is not a primitive, it cannot have a value (at start)'

In FHIR R4, example of Encounter is Encounter.period.start

so I can't understand why has this wrong text

Hi @huang-tzu, I am trying to figure out what you are doing here. Do you have a json file and you trying to parse it? Or are you performing a FhirPath expression to a Poco?

[huang-tzu]

thanks for your reply.
yes, I'm in performing a FhirPath expression to a Poco.
Procedre of resource doesn't have this type of problem.
for example,
Procedure.performedPeriod.end
using 2019-03-29T01:05

by the way
Encounter.period.end doesn't have any error text,too

I think you should provide us with a full snippet, including the json you are parsing otherwise we will not have enough context to help you.
