Hey, I am a new bee to fitbit development. right now, I am willing to learn for sense. but my fresh new application is not working. It says internal error. No matter i am running it with CLI or Fitbit Studio.
Both my phone and simulator have the same account. Companion and debugger both bridge are connected. Its getting build too. but when i try to install it. it says internal error.I am mentioning  my system details and Error details below.
