A cloud agent connection causes the screen to go blank #11

Closed b1conrad closed 4 months ago

b1conrad commented 3 years ago

Matthew Hailstone created a connection between a thing (with the manifold_cloud_agent app installed) and his Evernym connect.me wallet. Not sure how far along the connection got, but now the screen goes blank when he opens up that agent.

To do: have him show the exact symptoms.

When he visits this page (while logged in as himself), "Just keeps spinning and doesn’t come up."

To do: watch over his shoulder as this happens and have him try a few things.

The only thing suspicious on the pico side is that the crippled connection doesn't have a key their_endpoint which could produce a run-time error in the browser, since JavaScript... Never mind, it should just be undefined but perhaps that causes a problem downstream.

This would happen here and here.

The field, renamed endPoint and then (surprisingly) invitation is used as part of the id for the input field to send a basicmessage. I don't know what would happen when it is undefined. Let's simulate this...

Looks like you would see this error message in the browser console, "Uncaught TypeError: Cannot read property 'concat' of undefined" and then the page would never finish loading.

For Matthew's case, removed the crippled agent from his pico's list of connections by sending a well-crafted /sky/event/ to it. That solves his immediate problem.

We still need to make the page more robust.

The issue has been resolved, for this owner, for this case. Issues have been raised in two other repositories to improve robustness.

We will do nothing further with this issue here. When moving to the v1 pico engine (issue #9) we will not use the Manifold Cloud Agent app, because we will only support DIDComm v2 going forward.
