Hi folks, hope y'all are doing great!

I deployed my first portfolio website and wanted to see the lighthouse score. It decreases 5 points from the best practices criteria since errors are logged into the console and I noticed that there is a console error as in the picture. I can't figure out what this error is and find any source on Google. Can I have your help please?
