Unable to Init Publisher

[reka18]

Running the example locally I am getting the following issue. This happens intermittently, but even when it doesn't happen the example code submits nothing to my topic when I add the relevant environment variables.

          /\      |‾‾| /‾‾/   /‾‾/   
     /\  /  \     |  |/  /   /  /    
    /  \/    \    |     (   /   ‾‾\  
   /          \   |  |\  \ |  (‾)  | 
  / __________ \  |__| \__\ \_____/ .io
