In order to resolve the error “TypeError: Cannot read property ‘getBoundingClientRect’ of null”, you’ll need to make some adjustments in your code. Specifically, ensure that ‘pdfWrapper’ exists and has a ‘current’ property before using it, as demonstrated in the below code snippet:
const setPdfSize = () => { // check if 'pdfWrapper' exists and has a 'current' property before using it if (pdfWrapper?.current) { setInitialWidth(pdfWrapper.current.getBoundingClientRect().width); } };
