Invalid ARN Prefix, when using Execution ID in GetExecutionHistory

0

I'm trying to use the context object Execution ID as described here:

https://docs.aws.amazon.com/step-functions/latest/dg/input-output-contextobject.html

So I can call the getExecutionHistory API as a task in my step function so I can keep track of how many events happen and not go over the 25,000 threshold. However when I pass the $$.Execution.Id as a parameter to the API I get an Invalid ARN Prefix error.

What should I be doing differently? Can you not use the API to get a running Step Function's State Machine Event History?

When calling APIs from tasks, you need to pass the execution ARN instead of the execution ID. You can access the execution ARN from the context object like this: "Parameters": { "ExecutionArn": "$$.Execution.Arn" }
