Error using integer wavelet transform

I'm interested in decomposing the image using integer wavelet transform.
I have tried the following
liftscheme = liftwave('haar','int2int');
data = imread('image.jpg'); % the image is in unit8
[cA cH cV cD]=lwt2(double(data),liftscheme);
But I'm getting the following error. My MATLAB version is R2022a
Error using parseParameterInputsML
Expected a parameter name.
Error in coder.internal.parseParameterInputs (line 91)
pstruct = parseParameterInputsML({},parms,options,varargin);
Error in lwt2>lwtParser (line 443)
pArg = coder.internal.parseParameterInputs(parms,poptions,varargin{:});
Error in lwt2 (line 73)
[LS,ext,level,wv,isI2I] = lwtParser(lx,varargin{:});

[cA, cH, cV, cD] = lwt2(double(data), 'LiftingScheme', liftscheme);

It appears that liftwave returns a struct rather than an object. See the compatibility section for replacement code
