"sourceMaps is null" in Firefox Developer Edition

Question

In the debugging window of the developer console - I can see all my javascript resources listed, but in of them it just says sourceMaps is null.

The resources I'm trying to fetch are some minified jquery, and unminified, but consolidated javascript. The javascript does not contain a sourcemaps comment.

Any suggestions for how I'd resolve this?

Answer 1

I had the same issue. I resolved it by updating the about:config settings

Open about:config

Search for devtools.source-map.client-service.enabled

The value of this option should be true.
