Running example HelloWorld for AWS Toolkit/SAM. Can't find python3.8

Hello,

I've installed the AWS Toolkit and configured it properly.  When I select Run>Run I get the following:

docker ps
/usr/local/bin/sam build HelloWorldFunction --template /Users/jungerle/PycharmProjects/garner-dev/template.yaml --build-dir /Users/jungerle/PycharmProjects/garner-dev/.aws-sam/build
Building codeuri: /Users/jungerle/PycharmProjects/garner-dev/hello_world runtime: python3.8 metadata: {} functions: ['HelloWorldFunction']

Build Failed
Error: PythonPipBuilder:Validation - Binary validation failed for python, searched for python in following locations : ['/usr/bin/python'] which did not satisfy constraints for runtime: python3.8. Do you have python for runtime: python3.8 on your PATH?
SAM Build has failed: Command did not exist successfully, exit code: 1
5 has failed: Command did not exist successfully, exit code: 1

However, when I run the following in the pyCharm Terminal it works fine:

/usr/local/bin/sam build HelloWorldFunction --template /Users/jungerle/PycharmProjects/garner-dev/template.yaml --build-dir /Users/jungerle/PycharmProjects/garner-dev/.aws-sam/build

How can I get the Run to recognize Python3.8?  (BTW, I do have Python3.8 selected as the interpreter for the project) Thanks for your help.
