Error using VideoWriter to write video frames to a file

Hello, I am trying to save a video from a FLIR camera using the gentl adaptor.

            vid = videoinput('gentl', 1, 'Mono16');              
            src=getselectedsource(vid);
            vid.FramesPerTrigger=20;
            preview(vid);
            start(vid);
            stoppreview(vid);
            diskLogger=VideoWriter('D:\Temp\VidMatlab.mp4','MPEG-4');   % Use the MPEG-4 Codec
            open(diskLogger);
            vid.FramesAvailable
            data=getdata(vid,vid.FramesAvailable);
            numFrames=size(data,4)
            for x=1:numFrames
                 writeVideo(diskLogger,data(:,:,:,x));
            end
            close(diskLogger)
            

But I keep getting the error message

Warning: No video frames were written to this file. The file may be invalid. 
Error using VideoWriter/writeVideo (line 414)
Operands to the || and && operators must be convertible to logical scalar values.

OK its this:

                if (min(inputFrames(:)) < 0) || (max(inputFrames(:)) > 1)
                    error(message('MATLAB:audiovideo:VideoWriter:invalidRange', curDataType));

OK I have 2 errors:

1: data=getdata(vid,vid.FramesPerTrigger); rather than data=getdata(vid,vid.FramesAvailable)

2: For video, you must use Mono8

Maybe the debugger reveals some details. Type this in the command window:

dbstop if caught error

Then run the code again. If Matlab stops at the error, check which arguments are not scalar in line 414 of videoWriter.
