DevTools Failed to load source mapping: Unable to load http://localhost:60155/Plugins/site/bootstrap.min.css.map content: HTTP error: status code 404, net::ERR_HTTP_RESPONSE_CODE_FAILURE
Solution:

Edit the bootstrap.min.css file and delete it as follows:








The function of .map file: After the project is packaged, the code is compressed and encrypted, and if an error is reported at runtime, the output error message cannot accurately know where the code error is.

With map, you can act like unencrypted code, with the exact output of which line and which column is wrong.

Note: Generally speaking, map output needs to be prohibited when packaging the production environment, and the map file will cause the source code of the project to be leaked
