Training a Convolutional Autoencoder

I'm trying to train this simple convolutional autoencoder but I'm getting error on the training part. The error says the size of predictions and tragets are not the same. But When I check the network structure using the analyseNetwork function it seems that my input has the same size as my output. I can't find where is the error. Can someone help me?
Follows the code
datastore_MP = datastore("Tiles_MP1_100ov50\", "IncludeSubfolders",true, "LabelSource","foldernames");
images_MP = cell(numel(datastore_MP.Files), 1);
for i = 1:numel(datastore_MP.Files)
img_MP = readimage(datastore_MP, i);
[rows, cols] = size(img_MP);
images_MP{i} = img_MP;
end
encoderBlock = @(block) [
convolution2dLayer(3,2^(3+block), "Padding",'same')
reluLayer
maxPooling2dLayer(2,"Stride",2)
convolution2dLayer(3,2^(5+block), "Padding",'same')
reluLayer
maxPooling2dLayer(2,"Stride",2)];
net_E = blockedNetwork(encoderBlock,1,"NamePrefix","encoder_");
decoderBlock = @(block) [
transposedConv2dLayer(3,2^(5-block),"Stride",2)
reluLayer
transposedConv2dLayer(3,2^(1-block), "Stride",2)
reluLayer];
net_D = blockedNetwork(decoderBlock,1,"NamePrefix","decoder_");
inputSize = [100 100 1];
CAE = encoderDecoderNetwork(inputSize,net_E,net_D);
analyzeNetwork(CAE)
options = trainingOptions( "adam",...
"Plots","training-progress",...
"MaxEpochs", 100,...
"L2Regularization",0.001);
trainedCAE = trainnet(datastore_MP, CAE, "mse", options);

Hey, try changing 'trainnet' to 'trainNetwork'.
trainedCAE = trainNetwork(datastore_MP, CAE, "mse", options);
