Error running bootstrap model on fitlm function

I currently have the below code, but I keep receiving an error when trying to run the bootstrap. Could anybody explain why I might be receiving the below error? I have tried with and without the 'linear' argument.

X = [auto_df.displacement, auto_df.horsepower, auto_df.weight];

y = auto_df.mpg;

auto_mdl = fitlm(X,y, 'linear');

boot_auto_mdl = bootstrp(500, @fitlm, X, y, 'linear');

Error using internal.stats.parseArgs (line 42)

Wrong number of arguments.

Error in bootstrp>extractNameValuePairs (line 338)

= internal.stats.parseArgs(defSpecialArgs,defSpecialValues,specialArgs{:});

Error in bootstrp (line 142)

[weights, options, bootargs] = extractNameValuePairs(varargin{:});
