Manifold Cloud Agent UX error

[b1conrad]

When a connection is created, but is incomplete because it lacks their_endpoint, the UI will just hang. There will be an error in the browser console, but most people wouldn't see that, and there is no workaround. The thing containing this app and an incomplete connection will be unusable for this app. Other apps would still be okay.

See this issue (in the Manifold-production-instance repo) for full analysis.

The request here is that the React code be made more robust. The connection should still show, but the Messaging tab should be disabled (since it is useless without the endPoint anyway).

The actual problem is the concat function used with the "invitation" which might be undefined.

Consider why the id is constructed in this way, and simplify if possible. If desired to retain it, consider using + for string concatenation instead of concat. See the "Performance" paragraph in this doc.
