Question

I am creating AWS IOT rule using sdk from my code with lambda function as action. Rule is getting created successfully, but its not getting triggered. It will start getting triggered only after I go the the UI page select the action and click on update button on the right hand side.

Any help to resolve the issue will be helpfull.

I faced this problem today, this is my solution.

You need to add permission to your target lambda, you can create a lambda, then run this code. You need change the functionName first. Then go your target Lambda function and click the permission, you will see the permission in your left side.

response = client.add_permission(
 FunctionName='Lambda_Name',
 StatementId='FunctionPermission',
 Action='lambda:InvokeFunction',
 Principal="iot.amazonaws.com",
 SourceAccount = "yourAccount")
