Example fails to run install without amendments

[andrewdavidcostello]

#182

It looks like this commit breaks the example via the article process. Running install.sh leads to

      throw new Error(`${variableName} environment variable must be defined`);
            ^
Error: OIDC_CLIENT_ID environment variable must be defined

Removing the defined env check in the getEnv and setting fallbacks outside the method via ?? sorts it and have been able to run install.sh successfully. Can't comment on after as only got this far for now.

Hope this helps.

Thanks for raising this. These variables should indeed be optional. Resolved as of 1cdb2a7
