Loaded scripts: TypeError: Cannot convert undefined or null to object

[isidorn]

Start vscode out of source scripts/code.sh

Have the following js file console.log('hello there');

Start debugging it (you do not have to set a breakpoint). Notice the exception in the chrome dev tools console. Note that I can not repro with vsocde insiders.

If you pause on exception you can see this is coming from the loaded scripts view line 326

For a very short debuggee, the session is disposed before the tree is created.
