Line 795 in 1f0c3e4

let initializer = (defaultProps as ts.PropertyDeclaration).initializer;

@pvasek

and I add code before upper line

if (!initializer) {
                    console.log(symbol, source);
                    return res;
                }

bug fixed~

do you need PR?

If not , I only can fork this repo and publish anthor npm package for fix this
