title: `sam local invoke`error 'NameError: name 'NpipeHTTPAdapter' is not defined'
body: <p>I am writing a lambda function just to get some data from an AWS RDS table. I am able to successfully run <code>sam package</code> and <code>sam deploy</code> to deploy the function to AWS. </p>
  
  <p>When I run <code>sam build</code> it successfully builds and then I run <code>sam local invoke</code> to test the lambda locally, but I get the following error output</p>
  
  <pre><code>$ sam local invoke

  <p>Docker Desktop is also installed and running on my machine.  I have been on <a href="https://github.com/docker/compose/issues/4842" rel="nofollow noreferrer">https://github.com/docker/compose/issues/4842</a> and tried to install aws-sam-cli via the MSI but that did not work. I have reinstalled Python, AWS CLI, AWS SAM CLI, and Docker. I am not sure where to go next.</p>
  
  <p><strong>Is there any fix to get my AWS Lambda functions running locally?</strong></p>
