RoboHelp 2020 > Frameless HTML > Output warnings: "map" files

[Mark_Noc]

Hello! I get the following console errors when outputting Frameless HTML on Chrome:

DevTools failed to load SourceMap: Could not load content for https://docs.flightsimulator.com/html/template/Orange/orange.css.map: HTTP error: status code 404, net::ERR_HTTP_RESPONSE_CODE_FAILURE
DevTools failed to load SourceMap: Could not load content for https://docs.flightsimulator.com/html/template/scripts/topicpage.js.map: HTTP error: status code 404, net::ERR_HTTP_RESPONSE_CODE_FAILURE
DevTools failed to load SourceMap: Could not load content for https://docs.flightsimulator.com/html/template/Orange/orange.css.map: HTTP error: status code 404, net::ERR_HTTP_RESPONSE_CODE_FAILURE

On Firfox I only get one error about the "orange.css.map".

I have done a lot of searching and not found any explanation as to what these files are nor how to avoid getting these warnings. They don't seem to affect the pages, but I'm wondering if they may be related to other issues I have. Does anyone know what these "map" files are, and how to fix/remove the warnings I'm getting?

Note that even with the RH sample files I get these warnings so it's not related to my project, but rather to the frameless skin output (I have tested them all, and they all give this issue).

If you're getting the same sort of warnings with the sample projects, then that indicates that something is messed up in your install of RH. Have you tried uninstalling & reinstalling and updating the version already?

Hi Jeff! I have done a fresh install of RH, yes. The issue persists, regardless.

Ok, then I think you need to have a chat with Support - see https://helpx.adobe.com/contact/enterprise-support.other.html#robohelp for your support contact options.

Ha! Rubber ducking at it's best... Just after posting this I found an interesting article here:

https://css-tricks.com/should-i-use-source-maps-in-production/

The important part is this:

Shipping source maps to production is a nice middle ground. There’s no hit on performance (source maps don’t get loaded unless you have DevTools open, which is, IMO, irrelevant to a real performance discussion) with the benefit of delivering debugging and learning benefits.

So, it seems the warning is only generated because I have Dev Tools open and it has nothing to do with Robohelp. 🙂

Sorry, I completely missed that you were looking at the source code on the page - was reading them as actual messages that the page was throwing to the user.
