Vscode-react-native: Getting error 101 when debugging iOS

[kevinnguy]

Actual Behavior

Running my debug configuration for iOS doesn't work. I get the error:
Error while executing command 'react-native run-ios --scheme 'dev' --simulator='iPhone SE' --verbose --no-packager' (error code 101)

Debugging should work as normal

Hi @kevinnguy and thanks for reaching us. It seems that there is a = symbol is missing in the scheme declaration of your arguments. Could you please try to add it so the first argument will look like --scheme=dev?
Also as seen from your debug configuration, you can use special debug configuration parameters instead of runArguments such as scheme and target.
Here is the example of the debug scenario after changes:

    {
      "name": "Debug iOS",
      "cwd": "${workspaceFolder}",
      "type": "reactnative",
      "request": "launch",
      "platform": "ios",
      "scheme": "dev",
      "target": "iPhone SE"
    }

Please let us know if that was helpful.

@SounD120 thanks so much, it was using the scheme and target params that fixed the issue.
