Giving error in confusion plot

Dear

I am using the naive model for classification of emg signal. The below prgram run smoothly except the last line of confusion plot, show error.

Find the attached snapshot

load('FeatureAngle000Musscle1.mat')

X = FeaturesAngle000Muscle1(:,1:4); % feature numerical values

Y = FeaturesAngle000Muscle1(:,5); % response like handopen, handclose etc

rng(1); % For reproducibility

Mdl2 = fitcnb(X,Y,...

'DistributionNames',{'normal','normal','kernel','kernel'},...

'ClassNames',{'HandGrip','HandOpen','HandRest','WristExtension','WristFlexion'});

Mdl2.DistributionParameters{1,2}

isLabels2 = resubPredict(Mdl2); % it generate the output/response of model

ConfusionMat2 = confusionchart(Y,isLabels2);

Error using confusionchart (line 64)

First argument must be a numeric square matrix, cell array of character vectors, categorical, logical, string or numeric

vector, character array, or parent container.

ConfusionMat2 = confusionchart(table2array(Y),isLabels2);
