passing launch config without a 'type' attribute to 'vscode.startDebug' does not return an error

[weinand]

testing #6248:

• VSCode Version: 1.1.0 alpha
• OS Version: OS X 10

Steps to Reproduce:

• use the setup from launching debug via 'vscode.startDebug' API does not work if there is no launch config #6806
• remove the 'type' attribute
• run 'Hello' command

Observe:
no error is reported.

'type' is a mandatory attribute that should result in error if missing.
But it should be possible to omit attribute 'name' without error.

Currently the command returns the errors, after consulting with Joh it is the extensions responsibility to handle this error in any way the extension writer wants. Closing as designed. More details:

@isidorn What error is returned if attribute 'type' is missing?

With the commit I just pushed it returns a proper error message 😊

Maybe we should tune the error message such that it does not refer to launch.json
