After opening the service handle, which i believe is opened correctly, it is no longer allowing me to access anything from the server and comes up with the error blocked:

refServiceHandle: hopen 5010

// ex 1.5

refServiceHandle “tables”  
optRef: refServiceHandle(getOptionRef;uniqueOpts)

Hi ,

The reason you are getting this error is because it states in the question that the q process is restricted in that it only calls to it’s API’s (screenshot attached).

That’s why you can’t run commands such as ‘refServiceHandle “tables”’.

Also - to retrieve data from a connection you must use the symbol reference.

Hope this helps,

Megan
