Sandbox shuts down due to uncaught error in app code

[teleclimber]

If I add this line to leftovers handler:

export async function getCurrentUser(ctx:Context) {
	console.log( await fetch("http://olivierforget.net") ); // add this line
        //...

And if the request is rejected with an error of some sort, the sandbox shuts down.

error: Uncaught (in promise) TypeError: error sending request for url (https://olivierforget.net/#undefined): error trying to connect: invalid peer certificate: UnknownIssuer
	console.log( await fetch("http://olivierforget.net") );
	             ^

Although this could be due to my broken proxy? To investigate more.
