Using SnapLogic HTTP Client Snap to Connect AWS SageMaker with IAM Role Issues

Hello! Has anyone successfully used the SnapLogic HTTP client snap to connect to AWS SageMaker using an IAM role? We’re seeing that the role itself works when tested directly, we have manually entered the temporary credentials to validate and execute. However, when adding the role as an IAM Role ARN within the SnapLogic account settings, we see that SnapLogic is not able to connect and gives a nondescriptive error message (no API response at all). The temporary credentials entered by manually assuming the role work fine and we have tested the role within AWS, so the AWS side is valid. Only when the IAM role is set up for AWS SigV4 in Snaplogic does the issue appear. Any guidance or examples from others who’ve set this up would be greatly appreciated.
