AUthentication error in AWS Bedrock chat model node

Describe the problem/error/question When we try to configure the AWS Bedrock chat model, we are able to see the drop down of the models which shows that the credentials are good. But when we execute it using a Q&A Chain or even the embeddings node, we get the below error. Based on the search it looks like a AWS 4 signature issue. Can you please help?

What is the error message (if any)?

Hi @Vijay_Menezes, I am very sorry you are having trouble. I’ve requested access to AWS Bedrock in order to reproduce this problem as soon as I can - in the meantime can you confirm which n8n version you are currently using?
