I'm getting the following error when running cider-jack-in-cljs in emacs ,the selecting shadow as the repl type

@lilactown indeed karma works nicely. I am using playwright instead to run against three browsers at a time which is nice. Haven't tried it on CI yet but on Mac it works nicely.

^ also works fine on Travis after a few back-and-forth sessions.

Hi, I'm developing a web app and source maps work fine on desktop, but not on chrome for android (using the PC's devtools). The message (loads of other files) is: DevTools failed to load source map: Could not load content for http*/cljs-runtime/*.js.map: Fetch through target failed: Target not supported; Fallback: Unknown error Already checked that the URL is accessible in the mobile browser. Any ideas why? And is it possible to get it working? Thanks.

well if you truncate the error message it is really hard to tell what is going on

what Target is it trying to get? like what is the full url of the .map?

"Target" being the host address I'd presume?

maybe try setting :devtools {:loader-mode :script} in your build config

Sorry, thought it would be irrelevant, since the map file URL opens in the mobile browser successfully. The full path of one of the errors is https://host/cljs-runtime/goog.events.eventid.js.map.

is it a literal host? I mean this is the root of your problem. it doesn't help if you change it 😛

if you are trying to hide a IP then check if its the actual IP reachable by both the host PC and the Android device

Trying not to expose private info X). It's a FQDN, where the app is running. Like http://myapp.me.com

and that domain AND port is reachable by both?

Yes. It is the same base address in the browser's address bar. It's being served by an nginx proxying to shadow-cljs.

I've set :devtools-url in shadow-cljs.edn for it to work through https. In the repl I get to access the mobile browser's runtime

I assume this is using https? is the cert also valid on both devices?

I mean I don't know who is actually trying to get the source maps

sounds like the PC stuff is trying to get it over the android device

dunno what "Unknown error" means. doesn't seem like something shadow-cljs is involved in at all

Yes. Self signed, but I added it to both browsers and the app works fine, including the https exclusive stuff

hmm yeah but self-signed is always a problem. it might not be trusted by the devtools so thats why it might fail

get a letsencrypt cert. less hassle 😛

Good idea. Will get that and investigate devtools. Thank you for your help and for shadow-cljs!

I tested first without https, nginx, etc to see if I could reproduce the error. And it still happens: (this time verbatim) DevTools failed to load source map: Could not load content for http://192.168.10.100:5000/cljs-runtime/clojure.string.js.map: Fetch through target failed: Target not supported; Fallback: Unknown error DevTools failed to load source map: Could not load content for http://192.168.10.100:5000/cljs-runtime/shadow.remote.runtime.obj_support.js.map: Fetch through target failed: Target not supported; Fallback: Unknown error Just two examples. There are hundreds of lines like these. What I could identify is that the only file specific to my app is a web worker. My related :modules: :shared {:entries []} :main {:entries [main] :depends-on #{:shared} :preloads [dev-preload]} :worker-pricemeter {:init-fn workers.pricemeter/init :depends-on #{:shared} :web-worker true} Any ideas?

I also tried :loader-mode :script to no success
