It looks like there is a weird ".com" in the server base url, judging by the top of that stack trace.

I'd double check the base URL you are using to create the client.

Cheers,

James

Hmm.. Are you able to reproduce however you are calling this in an IDE with a code snippet? If so, can you post the code snippet that reproduces this?

Cheers,

James

Hi James,

I am getting the FHIR context and client form the below mentioned functions:-

protected FhirContext getFHIRContext()

{

FhirContext ctx = FhirContext.forDstu3();

if(proxyURL !=null && !(proxyURL.isEmpty()) && proxyPort !=0 )

ctx.getRestfulClientFactory().setProxy(proxyURL, proxyPort);

if(proxyUsername !=null && !(proxyUsername.isEmpty()) && proxyPassword !=null && !proxyPassword.isEmpty())

ctx.getRestfulClientFactory().setProxyCredentials(proxyUsername, proxyPassword);

return ctx;

}

protected IGenericClient getFHIRClient(FhirContext ctx,String facility_ID)

{

CASHISEndpoint e=searchEndPoint.getEndpoints(facility_ID);

System.out.println("In CASBASE Process:------------ "+e.getFacility_ID()+" "+e.getHis_EndPoint());

IGenericClient client = ctx.newRestfulGenericClient(e.getHis_EndPoint());

return client;

}

-----------------------------------------------------------------------------------------------------------------------------------

// get FHIR context

FhirContext ctx = getFHIRContext();

// get IGeneric Client

IGenericClient client = super.getFHIRClient(ctx,this.getLocationId().toString());

IQuery<ca.uhn.fhir.model.api.Bundle> query = client.search().forResource("Slot");

responseBundle = query.encodedJson().returnBundle(Bundle.class).execute();

It is giving me error on the last line which is highlighted.

one more info to add.....this code is working fine in my local environment. When i push this code to PREDIX platform the only i am facing the issue.

I hope i am providing the sufficient info. Kindly let me know in case you need any further info.

Thanks and Regards,

Sahil

If the same code works locally for you, that sounds like it's something specific to your environment. I would double check that the server you are deploying to has the appropriate permissions and firewall rules to be able to access the internet. Also double check the proxy settings you are using.

If there are any other stack traces in the error log that might also help.

Cheers,

james

Hi James,

I am also thinking in the same direction. This is issue with the environment settings. As i am novice to PREDIX,plus i dont have the admin access to the platform where i could see the configuration settings. Simultaneously i have opened the ticket with the PREDIX expert team. Waiting for their revert.

ll post the findings once i ll get their response.

Thank you very much for your valuable responses.

Regards,

Sahil

Hi All,

Apologies for posting it so late. This issue has been solved long back.

It was a proxy issue. Nothing related to FHIR.

Thanks a lot for your valuable inputs on this.

CHEERS... :)
