[adventmedia]

Plugin version:
5.0.1

Platform(s):
iOS 17.6.1, iPad Pro 3rd Gen.

Current behaviour:
Calls to KeepAwake in iOS app fail silently - no result returned (works just fine in desktop web browser)

Expected behavior:
Calls to KeepAwake should return result

Related code:
Code in app:

  private async checkIsSleepSupported() {
    console.log('checkIsSleepSupported', KeepAwake);
    try {
      const ok = await KeepAwake.isSupported();
      this.sleepSupported = ok.isSupported;
      console.log('sleep supported:', KeepAwake, ok, this.sleepSupported);
    } catch (err) {
      console.error('KeepAwake failed:', err);
    }
  }

Other information:
Console logs in desktop browser (Chrome):

checkIsSleepSupported 
sleep supported: Proxy(Object) {}  {isSupported: true} true

in Xcode console:

⚡️  [log] - checkIsSleepSupported {}
⚡️  [error] - KeepAwake failed: {"code":"UNIMPLEMENTED"}

This error does not come from the plugin, but from Capacitor. It appears that you have not installed the plugin correctly. Please take a look at the Capacitor iOS Troubleshooting Guide.

actually the problem appears to be that capacitor does not like mono-repos (I’m developing two apps with a lot of shared code). Wonder is that everything worked before except KeepAwake; now the app doesn’t run at all. Such fun.
