Error with specifying template analyzer environment variables

I am trying to use the action to analyze a single template, so I specified env variables that seem to correspond to the usage described in https://github.com/Azure/template-analyzer:

      - name: Run Microsoft Security DevOps Analysis
        uses: microsoft/security-devops-action@preview
        env:
          GDN_TEMPLATEANALYZER_VERBOSE: 1
          GDN_TEMPLATEANALYZER_ANALYZETEMPLATE: "infra/main.json"
          GDN_TEMPLATEANALYZER_PARAMETERSFILEPATH: "infra/main.parameters.json"
        id: msdo
        with:
          tools: templateanalyzer

However that results in a poorly formed command and subsequent error:

  Analyze:
    Using environment variable override: AnalyzeTemplate=infra/main.json
    Using environment variable override: ParametersFilePath=infra/main.parameters.json
    Using environment variable override: Verbose=1
    Running ARM Template Best Practice Analyzer 0.4.0

Here's the full workflow:

Can you clarify proper usage?
Thanks!

Start with the workflow shown in the issue and the templateanalyzer entry point selected by tools: templateanalyzer. Compare the environment-variable-derived arguments with the analyzer's supported command syntax; done means a single-template workflow runs without unrecognized-argument errors.
