Chained queries

06/24/2024, 5:34 PMHi guys, how are you!?
I need help with some queries I'm developing for the API. Sorry for my lack of knowledge, but if you can help me, I'd appreciate it!
For example, when I run the following query:
http://fhir-homolog.hydra.saude-go.net/fhir/R4/ImmunizationRecommendation?recommendation.vaccineCode=55&_format=json
I get the following result:
"resourceType": "OperationOutcome",
"issue": [
{
"severity": "error",
"code": "invalid",
"details": {
"text": "Invalid search parameter in chain: ImmunizationRecommendation?recommendation"
}
}
],
And also when I try to do a chained query, such as:
http://fhir-homolog.hydra.saude-go.net/fhir/R4/Immunization?_format=json&_count=10&_include=Immunization:patient&patient.address:city=521930
I also get the same error. Am I structuring something wrong in the query? Or do I have to do some configuration in Medplum?
Thank you so much guys! I hope you have help.

06/26/2024, 5:05 AMHi @Adriano Freitas - when doing this kind of search, you cannot search on arbitratry fields - You'll have to use the specified search paraeters

06/28/2024, 6:59 PMThat's right @rahul1 , sorry for the mistake! Thank you very much for the clarification! I have another question regarding GraphQL, any query we run on the endpoint returns:
"resourceType": "OperationOutcome",
"issue": [
{
"severity": "error",
"code": "structure",
"details": {
"text": "Unknown resource type"
}
}
],
Is this correct? Is there anything we can do differently? We tested all the examples available on the documentation page and were unsuccessful. We also tested by simply sending to the /$graphQL Endpoint and the return is always the same, regardless of what we send. Can you help us?

07/05/2024, 6:12 AM@Adriano Freitas could you share the exact graphql query you are running. It might be a simple syntax error

07/12/2024, 10:10 PMAny request I send returns this response. Can be anyone. Using POSTMAN, I access the GraphQL Tab and paste the following Medplum example expression:
{
PatientList(name: "Eve", address_city: "Philadelphia") {
resourceType
id
name {
family
given
}
address {
line
city
state
postalCode
}
}
}
The return is the same. If I delete this query, and just call /$graphql, the return is the same. I don't know what could be wrong.

07/23/2024, 5:56 PM@Adriano Freitas make sure to wrap the text in a "query" entry. The raw POST request would look somethng like this
> POST /fhir/R4/$graphql HTTP/2
> Host: api.medplum.com
> content-type: application/json
| {"query":"{\n PatientList(name: \"Eve\", address_city: \"Philadelphia\") {\n resourceType\n id\n name {\n family\n given\n }\n address {\n line\n city\n state\n postalCode\n }\n }\n}"}

08/12/2024, 7:01 PMGood afternoon @rahul1 ! We were able to help GraphQL in our environment, but we discovered something that we are unable to implement. When executing the query:
query {
ImmunizationRecommendationList(_id: "37b6695b-945f-5656-9842-dafb828a104a", vaccine_type: "34") {
id
patient {
reference
}
recommendation {
vaccineCode {
coding {
system
code
display
}
}
forecastStatus {
text
}
dateCriterion {
code {
coding {
system
code
display
}
text
}
value
}
doseNumberString
seriesDosesPositiveInt
}
}
}
We are unable to filter what only has vaccineCode = 34, but it returns the instance with all the values that we stored inside the Recommendation. Can you help me filter these instance values? Attached I will leave the Print of the response and an example of an instance we have of Recommendation.

08/23/2024, 5:12 AMHi @Adriano Freitas , Looking at the resource you attached contains the vaccine code "34"
Copy code
"system": "http://www.saude.gov.br/fhir/r4/CodeSystem/BRImunobiologico",
"code": "34"rahul1
08/23/2024, 5:13 AMThere is not a FHIR search that allows you to search recommendations that only has a code, and has no other codes
