why i'm getting this error?

program i run

[filename,pathname]=uigetfile('*','select a X-Ray image');
filewithpath=strcat(pathname,filename);
I=imread(filewithpath);
imResized=imresize(I,[[224 224]]);
    [class, score]=classify(netTransfer,imResized);
figure
    imshow(imResized)
    title([ 'Predclass=' char(string(class)),', ','score=',num2str(max(score)),', ','origClass=', char(string(imdsTest.Labels(1)))])

You need to input a RGB image i.e. the input jas to be m*n*3 dimensions. It seems you are reading a gray image i.e. a 2D image.

As per the error says, you have to pass the RGB images in this case to avoid this error, Although there may be others error too.
