X.js HTTP Error

[stevenburles]

Hi,

We’re having a couple of errors come up in the dev tools console:

• DevTools failed to load SourceMap: Could not load content for /wp-content/themes/pro/framework/dist/js/site/x.js.map: HTTP error: status code 404, net::ERR_HTTP_RESPONSE_CODE_FAILURE

• DevTools failed to load SourceMap: Could not load content for /wp-content/themes/pro/cornerstone/assets/dist/js/site/cs.0ce70e6.js.map: HTTP error: status code 404, net::ERR_HTTP_RESPONSE_CODE_FAILURE

From what i can tell these files do not exist, for instance I can find an x.js but not x.js.map.

Any ideas how this can be fixed?

Thanks

Hi @stevenburles,

Thanks for reaching out.

Those errors are just missing source-maps. They are requested by developer tools (especially in Safari) when possible, but won’t interfere with anything.

Basically it’s a way to map a combined/minified file back to an unbuilt state. When you build for production, along with minifying and combining your JavaScript files, you generate a source map which holds information about your original files. When you query a certain line and column number in your generated JavaScript you can do a lookup in the source map which returns the original location.

So, basically you can ignore those errors. Please check out this link for more information (https://stackoverflow.com/questions/19550060/how-do-i-toggle-source-mapping-in-safari-7/19823890#19823890).

Hope that helps.

Thank you.
