Sentry is looking for source map in cloud server

Hi! I’m having problems to use source maps in Sentry. I’m using sentry webpack plugin and it is working properly. It is uploading the minified file and its sourcemap, like this:


But looks like sentry is omitting them, because if I move the cursor to the question mark icon in the bug tracker I see that it is looking for the sourcemap in the same url of the original js file instead of artifacts.

What could be the reason?

Thanks in advance,
