People Counter Web App displays no data

Question

When I deployed the people counting web app demo, the app didn't seem to be pulling any data. It would say 0 piplines.

I contacted chat support earlier and a rep, Mallikarjun told me it seems the front end is okay, and that there may be an issue in the back end configuration.

I was following this documentation: https://learn.microsoft.com/en-us/azure/cognitive-services/computer-vision/spatial-analysis-container?tabs=azure-stack-edge

and used this deployment manifest: https://github.com/Azure-Samples/cognitive-services-sample-data-files/blob/master/ComputerVision/spatial-analysis/DeploymentManifest-NonASE.json because I am running the IoT Edge on a laptop with a GTX 1050ti.

In the manifest I modified the Compute Vision APIKEY value, Billing value.

I also replaced every single <Replace RTSP URL here> with my RTSP URLS. The RTSP URLS were confirmed to work on VLC and using " ffprobe -v quiet -print_format json -show_streams <RTSP URL>" worked.

I also tried sudo iotedge check and got passing checks.

Is there anyway I can get help troubleshooting this?

Configuration checks

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

√ config.yaml is well-formed - OK
√ config.yaml has well-formed connection string - OK
√ container engine is installed and functional - OK
√ config.yaml has correct hostname - OK
√ config.yaml has correct URIs for daemon mgmt endpoint - OK
‼ latest security daemon - Warning
Installed IoT Edge daemon has version 1.0.9.5 but 1.1.1 is the latest stable version available.
Please see https://aka.ms/iotedge-update-runtime for update instructions.
√ host time is close to real time - OK
√ container time is close to host time - OK
‼ DNS server - Warning
Container engine is not configured with DNS server setting, which may impact connectivity to IoT Hub.
Please see https://aka.ms/iotedge-prod-checklist-dns for best practices.
You can ignore this warning if you are setting DNS server per module in the Edge deployment.
‼ production readiness: certificates - Warning
The Edge device is using self-signed automatically-generated development certificates.
They will expire in 85 days (at 2021-07-29 22:13:27 UTC) causing module-to-module and downstream device communication to fail on an active deployment.
After the certs have expired, restarting the IoT Edge daemon will trigger it to generate new development certs.
Please consider using production certificates instead. See https://aka.ms/iotedge-prod-checklist-certs for best practices.
‼ production readiness: container engine - Warning
Device is not using a production-supported container engine (moby-engine).
Please see https://aka.ms/iotedge-prod-checklist-moby for details.
‼ production readiness: logs policy - Warning
Container engine is not configured to rotate module logs which may cause it run out of disk space.
Please see https://aka.ms/iotedge-prod-checklist-logs for best practices.
You can ignore this warning if you are setting log policy per module in the Edge deployment.
‼ production readiness: Edge Agent's storage directory is persisted on the host filesystem - Warning
The edgeAgent module is not configured to persist its /tmp/edgeAgent directory on the host filesystem.
Data might be lost if the module is deleted or updated.
Please see https://aka.ms/iotedge-storage-host for best practices.
‼ production readiness: Edge Hub's storage directory is persisted on the host filesystem - Warning
The edgeHub module is not configured to persist its /tmp/edgeHub directory on the host filesystem.
Data might be lost if the module is deleted or updated.
Please see https://aka.ms/iotedge-storage-host for best practices.

Connectivity checks

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

√ host can connect to and perform TLS handshake with IoT Hub AMQP port - OK
√ host can connect to and perform TLS handshake with IoT Hub HTTPS / WebSockets port - OK
√ host can connect to and perform TLS handshake with IoT Hub MQTT port - OK
√ container on the default network can connect to IoT Hub AMQP port - OK
√ container on the default network can connect to IoT Hub HTTPS / WebSockets port - OK
√ container on the default network can connect to IoT Hub MQTT port - OK
√ container on the IoT Edge module network can connect to IoT Hub AMQP port - OK
√ container on the IoT Edge module network can connect to IoT Hub HTTPS / WebSockets port - OK
√ container on the IoT Edge module network can connect to IoT Hub MQTT port - OK

16 check(s) succeeded.
7 check(s) raised warnings. Re-run with --verbose for more details.

@Tai Dao Thanks for the question. We would recommend to raise a Azure support desk ticket from Help+Support blade from Azure portal for your resource. This will help you to share the details securely and work with an engineer who can provide more insights about the issue that if it can be replicated.
