Refused to execute script from 'https://.../js/act.js' because its MIME type ('text/html') is not executable, and strict MIME type checking is enabled

Hey Replit community!
While trying to dynamically open a page and display some data I fetched from Node.js server, I’ve got an error in the console Refused to execute script from 'https://.../js/act.js' because its MIME type ('text/html') is not executable, and strict MIME type checking is enabled. In total I have 2 pages which fetch the data from server and display it in browser. With the first page (account.js) I have no problems, it works perfectly, but after connecting second page (which works the same way - gets server’s data and displays it) I’ve discovered this error. First page still works fine but the second doesn’t.

Also, the console shows an 404 error ‘act.js’ not found, however such file is presented and its directory is used via app.use(). Here are the screenshots:

When I include the contents of the script file into EJS file (pure <script></script> tags without src attribute specified), everything works fine. May it be a bug of Replit that doesn’t see the file?

What should I do to fix the error?
