&nbsp;Hi team,  
while completing my level-2 certification, facing below issue on task 1.5 :

So I have created handle to get data from port 5457, using :

**refServiceHandle:hopen `::5457**

But when I am trying to call&nbsp;getOptionRef api, I am getting BLOCKED error.  
Please check screenshots.

getOptionRef should be a symbol, not a string:  
  
refServiceHandle(`getOptionRef; uniqueOpts)
