powertune-lambda returns only functionName

[dobeerman7]

I was trying to tune my lambda, but faced the execution problem:

$ lumigo-cli powertune-lambda -n xxx-dev-xxx -r eu-central-1 -s cost -i 10
checking the aws-lambda-power-tuning SAR in [eu-central-1]
the latest version of aws-lambda-power-tuning SAR is 3.2.4
looking for deployed CloudFormation stack [serverlessrepo-lumigo-cli-powertuning-lambda] in [eu-central-1]
stack is deployed and up-to-date
the State Machine is arn:aws:states:eu-central-1:xxxxxxxxxxxx:stateMachine:powerTuningStateMachine-IVMxiPxxxxxx
State Machine execution started
execution ARN is arn:aws:states:eu-central-1:xxxxxxxxxxx:execution:powerTuningStateMachine-IVMxiPxxxxxx:9db4e1d2-642d-43ae-b02f-94037dee8079
........
{
  "functionName": "xxx-dev-xxx"
}

Any suggestions?

@dobeerman7 I think the step function has silently failed, can you pop into the Step Functions console and have a look at the execution?

@theburningmonk state machine execution was successful, but the following error:

  }
}

But, I might confirm, function was executed successfully, coz I surprisingly found 1k results of execution on another service :)

@theburningmonk @dobeerman7

I have exactly the same issue. How did you solve it?
{
"error": "ResourceNotFoundException",
"cause": {

@ninaraminelli were you able to find a solution? I ran into the same issue
