create_from_edge_environment()'s get_twin() is not returning the module twin values

[ismaan1998]

Issue-

I'm reading module twin properties in my edge module.

When i'm using -

client = IoTHubModuleClient.create_from_connection_string("HostName=example.azure-devices.net;DeviceId=example;ModuleId=ExampleModuleId;SharedAccessKey=somekey")
client.get_twin()

I'm able to get the module twin values from ExampleModuleId but when we're using -

client = IoTHubModuleClient.create_from_edge_environment()
client.get_twin()

It's returning - .

{'desired':{}, 'reported':{}}

Note - I'm running this code in edge environment.

Let me know if anything other details needed to debug the issue.

Thanks for bringing this to our attention. I'm going to look into this

@cartertinney any update on this?

@ismaan1998 So far, I have been completely unable to replicate it. I'm reaching out to our Edge team to see if they have any additional insights, but any additional information or logs you can provide will be helpful.

It appears the issue may be with your configuration of the Edge. Could you provide us the Edge logs using the command
iotedge support-bundle so that we can take a look at what's going on?

@cartertinney Let me know if anything else needed

Apologies for the delay, we're still trying to get this looked into.

Hi @ismaan1998 - The iotedge check output is showing a lot of connectivity errors. Can you try adding a daemon.json file specifying the DNS server as described here and then repost your support bundle? https://docs.microsoft.com/en-us/azure/iot-edge/troubleshoot-common-errors?view=iotedge-2020-11#edge-agent-module-reports-empty-config-file-and-no-modules-start-on-the-device

Also, is there a proxy server in use on your network? If so, you'll need to follow the steps here to configure IoT Edge to use the proxy: https://docs.microsoft.com/en-us/azure/iot-edge/how-to-configure-proxy-support?view=iotedge-2020-11
