how to unset firebase cloud functions environment variable

问题

I have tried using command line functions:config:unset es.tipsinstitue.type as it is given here Environment Configuration. But this does not work for me. It gives me following exception.

 The filename, directory name or volume label syntax is incorrect.

Please help me.

Don't know whether it is documentation bug or not. Use firebase functions:config:unset es.tipsinstitue.type instead of functions:config:unset es.tipsinstitue.type. This will remove your environment variable
