Batch Commands in Private Instance


I am trying to execute multiple WebPageTest CLI commands from text file using webpagetest batch api in private instance

But am not able to execute as i was getting the below exception thrown in the console

error: option `-s, --server ’ argument missing

Command Provided in the text file:
test --location Test:Firefox --first --ignoressl -s “”

Command Provided to execute the batch:
webpagetest batch

If anyone has working soluition for batch execution in private instance , suggest what changes needs to be done to get it working

It would be helpful if any working example is posted
