I have created two C# IoT edge modules one for the sender and another for the receiver using IoT module routing. It is working fine and I got the data in the receiver module. But I had to change the sender module as python instead of C#. For the Python module, I had to debug as attach remotely debugging. While debugging in remoteley it shows the error like
Failed to attach (connect ECONNREFUSED 127.0.0.1:5678)
My lauch.josn file like
"name": "SenderPythonModule Remote Debug (Python)",
"type": "python",
"request": "attach",
"port": 5678,
"host": "localhost",
"logToFile": true,
"redirectOutput": true,
"pathMappings": [

"localRoot": "${workspaceFolder}/modules/SenderPythonModule",
"remoteRoot": "/app"
}
],
"windows": {
"pathMappings": [
{
"localRoot": "${workspaceFolder}\\modules\\SenderPythonModule",
"remoteRoot": "/app"
}
]
}
}
My main.py file like
import time

import sys
import asyncio
from six.moves import input

from azure.iot.device.aio import IoTHubModuleClient
import ptvsd
ptvsd.enable_attach(('0.0.0.0', 5678))

raise Exception( "The sample requires python 3.5.3+. Current version of Python: %s" % sys.version )
print ( "IoT Hub Client for Python" )

print ( "The sample is now waiting for messages. ")
# Run the stdin listener in the event loop

user_finished = loop.run_in_executor(None, stdin_listener)
# Wait for user to indicate they are done listening for messages
await user_finished

await module_client.disconnect()

print ( "Unexpected error %s " % e )
raise

loop.run_until_complete(main())

My routing like
"routes": {
"SenderPythonModuleToIoTHub": "FROM /messages/modules/SenderPythonModule/outputs/* INTO BrokeredEndpoint(\"/modules/ReceiverCSharpModule/inputs/input1\")",
"sensorToReceiverCSharpModule": "FROM /messages/modules/SimulatedTemperatureSensor/outputs/temperatureOutput INTO BrokeredEndpoint(\"/modules/SenderPythonModule/inputs/input1\")",
"ReceiverCSharpModuleToIoTHub": "FROM /messages/modules/ReceiverCSharpModule/outputs/* INTO $upstream",
},
Can anyone help me to figure it out? I am using windows os system.
