AWS Polly HTTP request node can't authenticate

I think the issue might be that you are expecting the parameters for an AWS SDK client call to work directly in an HTTP request.

Others have tried to do this sort of thing on other services too, with similar results.

I don’t think it is meant to work that way.

You could try one of the following:

  • Import and enable an external JS library for @aws-sdk/client-polly and use a code node to call Polly using the SDK
  • Implement a custom node that works like the other AWS nodes.
  • Install the AWS CLI in your n8n runtime environment (container?) and execute an AWS CLI command
