Bug: Incorrect error message for IdempotencyAlreadyInProgressError when sortKeyAttr is in use

[leandrodamascena]

Expected Behaviour

Original issue: aws-powertools/powertools-lambda-typescript#3691

When an IdempotencyAlreadyInProgressError is thrown, the error message should include the hashed key information.

Current Behaviour

Currently, the error message only includes the partition key, but when a sortKeyAttr has been provided in the config the partition key is a static string. The leads to meaningless errors in the log that all say there's a IdempotencyAlreadyInProgressError error for the same key.

Code snippet

no code

Possible Solution

Include both the pk/sk, or detect the current scenario better and include the more meaningful one.

Steps to Reproduce

use Idempotency with SK

Powertools for AWS Lambda (Python) version

latest

AWS Lambda function runtime

3.13

Packaging format used

Lambda Layers, Serverless Application Repository (SAR) App, PyPi
