Missing *.min.js.map files when aggregation is on

Hallo, I'm trying to find why Views preview button stopped working and in logs I found some cases of missing js files for anonymous and admin as well

page not found	12/27/2021 - 11:27	/sites/default/files/js/optimized/index.umd.min.js.map	
page not found	12/27/2021 - 11:27	/sites/default/files/js/optimized/jquery.once.min.js.map	
page not found	12/27/2021 - 11:27	/sites/default/files/js/optimized/backbone-min.map	
page not found	12/27/2021 - 11:27	/sites/default/files/js/optimized/once.min.js.map

my question is: could this be a reason? or if not, how to make this work?

Many thanks.
