Hello,
Thank you for contacting Rank Math and sorry for any inconvenience that might have been caused due to that.
I can confirm that the file is minified. It is likely that the first line on the file is what is causing the false positive:
/*! jQuery v1.12.4 | (c) jQuery Foundation | jquery.org/license | WordPress 2019-05-16 */
I can suggest that you ignore this error since clearly it won’t affect your site performance.
Looking forward to helping you. Thank you.
