Please provide us with the following information:

This issue is for Interval parameter: (mark with an x)

- [X] bug report -> please search issues before submitting
- [ ] feature request
- [ ] documentation issue or request
- [ ] regression (a behavior that used to work and stopped in a new release)

Minimal steps to reproduce

docker run -it -e "IotHubConnectionString=HostName=your-iothub-name.azure-devices.net;SharedAccessKeyName=device;SharedAccessKey=your-iothub-key" mcr.microsoft.com/oss/azure-samples/azureiot-telemetrysimulator -e Interval=30000 -e DeviceList="mydevice"

Any log messages given by the failure

No errors but printing message shows Interval = System.Int32[]ms and the message is sending at 1000ms rate.

Expected/desired behavior

message sending at 30s interval.

Could you please try if either of these works?

docker run -it -e "IotHubConnectionString=HostName=your-iothub-name.azure-devices.net;SharedAccessKeyName=device;SharedAccessKey=your-iothub-key" mcr.microsoft.com/oss/azure-samples/azureiot-telemetrysimulator -e WaitIntervals=30000 -e DeviceList="mydevice"

docker run -it -e "IotHubConnectionString=HostName=your-iothub-name.azure-devices.net;SharedAccessKeyName=device;SharedAccessKey=your-iothub-key" mcr.microsoft.com/oss/azure-samples/azureiot-telemetrysimulator -e WaitIntervals=[30000] -e DeviceList="mydevice"

@gukoff when I try to use WaitIntervals (either), I get the below error prompt
