Why do I get a 'Subscript indices must either be real positive integers or logicals' error when I try to read the waveform data from my oscilloscope using the Instrument Control Toolbox?

I have set up a connection with my PC and my oscilloscope using the Instrument Control Toolbox. However, when I try to use the 'readwaveform' function to get the output of my oscilloscope, I get the error as stated in the title. What does this mean in the context of trying to get the waveform data?

I understand what the error means with regards to a data array as you have described. What I am wondering is why I am getting this response from Instrument Control Toolbox and how do I get around it?
