(step-functions): Bug with payloadResponseOnly attribute of LambdaInvoke #12935
Description
There is an issue with payloadResponseOnly attribute of LambdaInvoke class.
Reproduction Steps
const getRDSInstanceStatus = new tasks.LambdaInvoke(this, GET_RDS_INSTANCE_STATUS, {
comment: 'Gets RDS Instance Status for FRS',
lambdaFunction: rdsProvisioningHandler,
payloadResponseOnly: true,
resultPath: '$.output.FrsAfe3SetupStateMachine.GetRDSInstanceStatus',
payload: sfn.TaskInput.fromJsonPathAt('$.input.FrsAfe3SetupStateMachine.ProvisionRDSInstance')
});What did you expect to happen?
Expected: When this property is set to true it should only copy the response payload to the output instead of adding response metadata.
What actually happened?
Actual: When this property is set to true, it distorts the function parameters defined in state machine.
