Hello,

I have downloaded hapi-fihr cli 3.4.0 and managed finally to upload some test data to my server from the SMART project (Using STU3 and the node tool)

My server uses the Hypersonic db and I can't query the collections because I always have a

ca.uhn.fhir.rest.client.exceptions.FhirClientConnectionException: Failed to parse response from server when performing GET to URL http://localhost:700

0/baseDstu3/Patient?_pretty=true - java.net.SocketTimeoutException: Read timed out

when searching for patients without parameters, even if I limit my result set to one element.

I suspect the default timeout for the http client is too small - is there a way to configure this since I am using the binary cli distribution ?

Kr,

Guido Amabili

Hi Guido,

There are instructions on how to change the client socket timeout here: http://hapifhir.io/doc_rest_client_http_config.html

That said, I have never seen the CLI server need a change to the socket timeout, so I'm doubtful that this will help. Are you sure you have the correct port? Does the same search work if you do it in a browser? How long does it take if so?

Cheers,

James

Hi James,

I am using Browser and the hapi-fihr Web UI to execute my queries.

A NullpointerException exception is raised here ca.uhn.fhir.to.BaseController.processAndAddLastClientInvocation(BaseController.java:634) - see below.

I don't know if this is related to the data I have uploaded since the HL7 examples can't be imported.

c.u.f.t.BaseController Failure during processing

java.lang.NullPointerException: null

This is the full stacktrace
