FitBit OS Simulator shows "Dang! Simulator Failed to Start. Try again." on command-line deployment

[hydralien]

Tried to wipe everything clean (the app and all traces in ~/Library; I'm using OSX) - but still, when I do 'build' and 'install' in a CLI, I see this:

App install complete (full)
Launching app
[10:39:26 PM]       App: App Closed
Device 'Versa 2 Simulator' disconnected

And in the simulator I see "Dang! Simulator Failed to Start. Try again."

package.json dependencies:

    "@fitbit/sdk": "~4.2.1",
    "@fitbit/sdk-cli": "~1.7.3"

Also, it works fine when deploying from FitBit Studio in browser - but not from CLI.

Anyone else faced similar issue?

Thanks!

Is it exactly the same project which is failing, or does it have a different ID? Are there any other differences in the project which works? Is it particularly large?

[hydralien]

Yes, exactly same project and exactly same code (copied from IDE - pasted into FitBit Studio editor). It's relatively simple watchface, so I wouldn't expect it to be heavy (if judging from the app.fba size in build/ directory, it's 23K). Note that install phase goes well, but it dies on launch attempt.

Here's what I see in the simulator log when trying to launch the locally built app:

 To compare, when launching the app from Studio, the log looks like this:

[hydralien · Accepted solution]

OK I think I found the problem - after answering "the code is the same" I realised that the only thing I could not sync to the Studio was package.json, so I downloaded the code from the Studio and compared the two - the one from Studio worked, while my original did not.

After some trial-and-error lines removal, turned out it was in "i18n" section - at some point I saw some warnings about missing description, repository and license info, so I (probably erroneously) decided those should be defined in the i18n section so it looked like this (not working):

"i18n": {
      "en": {
        "name": "Funktional",
        "description": "Functional watchface",
        "repository": "https://github.com/hydralien/FitBit-Funktional-Watchface",
        "license": "MIT"
      }
    }

Curiously enough, if I remove the "repository" value, it works - so this is OK (even though it might still do nothing):

"i18n": {
      "en": {
        "name": "Funktional",
        "description": "Functional watchface",
        "repository": "",
        "license": "MIT"
      }
    }
