Uncaught TypeError: Cannot read properties of null (reading 'addEventListener')
Can you please help me to get rid of that error at metronic8. I'm getting
Uncaught TypeError: Cannot read properties of null (reading 'addEventListener')" error even if I created assets according to your tutorial video about building assets. Do I have to add search.js to html or not? I'm newbie 
When I delete header search, the errors goes too. Here you can check the example: <a>

Hi,
The issue is due to a missing HTML element with data-kt-search-element="advanced-options-form-show" attribute. Can you please double-check the HTML code of the header search and add this element by referring to the original HTML templates?
Or you can update the core/html/src/js/layout/search.js with this version in order to be able to remove unused search icons(preference panel toggle icon, etc).
Then recompile your assets folder with Gulp or Webpack.
Please note that the build tools are required only in the development environment just to compile the assets when the source folder files are modified. In the hosting/server deployment, you will only need the compile assets, no need to install the build tools dependencies there.
Regards.
Thank you, the problem solved!
