MIME related header issue after file upload.

[ZigglerPL]

Hello, what should I do to completely get rid of the data stored in the browser’s memory, because I have a problem with the browser sending a request to a path that no longer exists, while the page on which the request is sent contains a different path?
The path of the current page looks like this: /saves/abc/,
And the one the browser refers to is as follows: /saves/
I have tried clearing the browser memory many times at the settings level in the chrome://settings/privacy tab and at the developer tools level.
As a result I get an error: [Failed to load module script: Expected a JavaScript module script but the server responded with a MIME type of “text/html”.
The error in this case does not include an endpoint for file requests.
Still, I get the correct code to respond, even though I don't even handle it in any way on the server side.
