NetworkError: Failed to execute 'send' on xmlhttprequest. Failed to load resource on cerner secure sandbox

[thiyagu83.j]

Hi,

Iam going to fetch the patients who are all having appointments for the selected date using authentication cerner sandbox.
After successfull authentication i can able to fetch the appointments for the selected dates by using the below URL with auth token,
https://fhir-ehr.sandboxcerner.com/dstu2/0b8a0111-e8e6-4c26-a91c-5069cbc6b1ca/Appointment .
After getting the patient Ids from the appointment iam going to fetch the patient information like Temperature,Weight, height, systolic BP,Glucose Fasting,RBC,WBC Intra Ocular Pressure left and right, Visual acuity left & right and glaucoma by using the below following Condition & Observation resources with authe token,

For Observation with AuthToken, https://fhir-ehr.sandboxcerner.com/dstu2/0b8a0111-e8e6-4c26-a91c-5069cbc6b1ca/Observation?patient=7586007
For Condition with AuthToken, https://fhir-ehr.sandboxcerner.com/dstu2/0b8a0111-e8e6-4c26-a91c-5069cbc6b1ca/Condition?patient=7586007

But i got error for both Condition & Observation resources,
NetworkError: Failed to execute 'send' on 'XMLHttpRequest': Failed to load 'https://fhir-ehr.sandboxcerner.com/dstu2/0b8a0111-e8e6-4c26-a91c-5069cbc6b1ca/Observation?patient=758600'

Observation resource: X-Request-Id: ea7db0f2-679f-4acd-82f3-8452cb714477
Condition resource: X-Request-Id: ffe48675-7cef-4511-83fb-646d2f270bc5

Can anybody please help what am i doing wrong.

Hi Thiyagu,

I looked for those two X-Request-Id values in the logs and could not find them. Can you explain a bit more about exactly what request provided them to you?

I can see successful (HTTP 200) responses for your application in the logs over the past few days. I notice that nearly all of your Condition and Observation requests use HTTP method OPTIONS instead of GET.

I would look into the following:

• The error message "Failed to execute 'send' on 'XMLHttpRequest'" makes me think that perhaps requests are not even making it out to Cerner's FHIR server
• Ensure you are consuming fhir-client.js in such a way that it issues GET requests

Cerner exposes the Practitioner search API for both DSTU 2 and R4, please consume that API to find practitioner IDs.

Thanks,

Max (Cerner)

Hi Max,
	Thanks for the reply.
	Actually i can able to get the auth token successfully. After that iam requesting appointments for selected dates by using below URL and get successfull responses.
	https://fhir-ehr.sandboxcerner.com/dstu2/0b8a0111-e8e6-4c26-a91c-5069cbc6b1ca/Appointment
	With that response i take the patientID and request for patient basic information using the below URL. I got successful response
	https://fhir-ehr.sandboxcerner.com/dstu2/0b8a0111-e8e6-4c26-a91c-5069cbc6b1ca/
	After that i request for observation resource for getting patient blood pressure,.. etc using below URL
	https://fhir-ehr.sandboxcerner.com/dstu2/0b8a0111-e8e6-4c26-a91c-5069cbc6b1ca/Observation?patient=" + PatientID
	with auth token but i got error as like below 
	NetworkError: Failed to execute 'send' on 'XMLHttpRequest': Failed to load 'https://fhir-ehr.sandboxcerner.com/dstu2/0b8a0111-e8e6-4c26-a91c-5069cbc6b1ca/Observation?patient=758600'
	
	I tried in many ways but i could not able to move a bit.
	
	I will try with method 'OPTIONS' and let you know.
	Iam authenticating using FHIR.oauth2.authorize({}) and getting the auth token using FHIR.oauth2.ready(function(smart) { });
	After that iam requesting the appointments, patients, condition, Observation using ajax method as like below,
	
	$.ajax({
			type: "GET",
			headers: {
                        Accept: "application/json+fhir",
                        "Content-Type": "application/json+fhir",
						"Authorization":"Bearer " + authToken    
				     },
			url: "https://fhir-ehr.sandboxcerner.com/dstu2/0b8a0111-e8e6-4c26-a91c-5069cbc6b1ca/Observation?patient=" + PatientID,
			dataType: "json",
            async: false,
            success: function (response) {
			
			}
			});
	I will try method OPTIONS and let you know.
	
	Please suggest me what am i wrong.
	
	Thanks,
	Thiyagu.

Hi Max,

I tried the method OPTIONS in my request but it gives me error.

Thanks,

Thiyagu.

[thiyagarajan jagan]

Hi Max,

Any update? I could not access the condition resources after authentication. 

It displayed error message as Access to Xmlhttprequest at '  '  from origin has been blocked by CORS policy.

Can you please help me on this max.

Thanks,

Thiyagu.

[Max Philips (Cerner)]

Hi Thiyagu,

Unfortunately we cannot offer to troubleshoot generic errors or generic error messages. Per group rules, please provide X-Request-Id response header values for the failures you are receiving.

If you are receiving CORS errors, please additionally provide the origin you are issuing requests from and the origin you are issuing requests to (assuming this is Cerner's sandbox).

Thanks,

Max (Cerner)

[thiyagarajan jagan]

Hi Max,

I resolved the issue. Issue due to scope was mismatched. I enabled both user scope and patient scope. Actually the user scope should be enabled. No patient scope should be enabled.

Another issue I got was while connecting patient resource I got 500 internal error. Attached image with x request ID for your reference.

Thanks,

Thiyagu.
