[karma-server]: UncaughtException:: file.detectType is not a function

[gonzojive]

Please see the Karma project's karma-runner/karma#3537, where they say the issue is with rules_nodejs.

Confirmed: karma ^5.1.0 breaks the implementation of concatjs. The right fix to to convert bundledFile (here) to a File. I suspect this could be done by importing {File} from @types/karma, if it's exposed.

[sgammon]

for anyone encountering this, i was able to work around it with the following pinned versions in package.json, which roughly match the rules_nodejs deps:

    "karma": "~4.1.0",
    "karma-coverage": "^2.0.1",
    "karma-chrome-launcher": "^3.1.0",
    "karma-firefox-launcher": "^2.1.0",
    "karma-jasmine": "2.0.1",
    "karma-jasmine-html-reporter": "^1.5.2",
    "karma-requirejs": "1.1.0",
    "karma-safari-launcher": "^1.0.0",
    "karma-sourcemap-loader": "0.3.7",

I am encountering the same issue. In my case it was enough to change the version of karma to

"karma": "~4.4.1"

The error occurs after upgrading karma to v5

I'm still having this issue. Posting this so the bot doesn't close it. Currently working with karma: 5.0.6 but breaks with 6.3.2.

Edit: Can we import File from karma/lib/file.js and make bundleFile an instance of it? I might give this a try.
