Error using sequenceInputLayer, Invalid argument at position 1. Expected input to be a scalar, 3 element vector or 4 element vector. Should i fill something in inputsize??

Please help me, i really have no idea. Im error using sequenceInputLayer.

here's the sequenceInputLayer code :

arguments
    inputSize {mustBeNumeric, mustBeNonempty, mustBeValidScalarOrRowVector(inputSize), ...
        mustBeReal, mustBeFinite, mustBeInteger, mustBePositive}
    nameValueArgs.Normalization {iValidNormalization} = 'none';
    nameValueArgs.NormalizationDimension = 'auto';
    nameValueArgs.Name {iAssertValidLayerName} = '';
    nameValueArgs.Mean = [];
    nameValueArgs.StandardDeviation = [];
    nameValueArgs.Min = [];
    nameValueArgs.Max = [];
    nameValueArgs.AverageImage = [];
end

and this is the layer's code

layers = [ ...
    sequenceInputLayer([n_samples,numFeatures])
    convolution1dLayer(filterSize,numFilters,'Padding','same')    
    eluLayer
    maxPooling1dLayer(3, 'Stride', 2)
    flattenLayer
    fullyConnectedLayer(numClasses)
    softmaxLayer
    classificationLayer];

Your release does not support 1D sequence input. The first release that supported that was R2021b
