Hi @MEPalma,
I've been testing the latest version and it seems the issues with reading from S3 are resolved. However, it looks like there's a similar problem when writing to S3.

Here's the step I'm trying to execute:

{
  "StartAt": "Write manifest file",
  "States": {
    "Write manifest file": {
      "Type": "Task",
      "OutputPath": null,
      "ResultPath": null,
      "Resource": "arn:aws:states:::aws-sdk:s3:putObject",
      "Parameters": {
        "Bucket": "bucket",
        "Key.$": "States.Format('backfills/v1/{}/manifest.json', $.backfill.id)",
        "ContentType": "application/json",
        "Body": {
          "backupDateTime.$": "$.backfill.backupDateTime"
        }
      }
    }
  }
}

And the error I'm getting is:

[-1695 (eval)] l.s.s.a.c.eval_component : Exception=FailureEventException, Error=States.Runtime, Details={"taskFailedEventDetails": {"error": "States.Runtime", "cause": "'dict' object has no attribute 'tell'"}}

I'm using AWS CDK with TypeScript. Interestingly, if I build the Body with the following code: Body: { backupDateTime: '12345'} It doesn't work. However, if I change it to: Body: JSON.stringify({ backupDateTime: '12345' }) It works.

Thanks for your help!
