echarts.min.js:22 Uncaught TypeError: Cannot read properties of null (reading 'getAttribute')

This error occurs when the script is trying to read the attribute of a null element. This can happen when the element that the script is trying to access does not exist in the DOM or has not been loaded yet.

To fix this error, make sure that the element exists in the DOM and is loaded before the script is executed. You can also try wrapping the script in a document.ready() function to ensure that the DOM is fully loaded before the script runs.
