Cannot read property 'hudScriptTemplate' of undefined error on 1st request

node v6.5.0 on OSX

When I start my express app and load the first page I see this glimpse error:

If I reload the page, the app starts working correctly. This only seems to happen on the first request after app startup. The glimpse HUD is visible on the page and otherwise seems to be working.

Thanks for the report @focusaurus.

We've got this assigned to @avanderhoorn. He'll take a look and report when we can get a fix out.

[mike-kaufman]

We took a fix last week for some of the "unexpected context" errors, so hopefully a new build will clear those up.

RE the Cannot read property 'hudScriptTemplate' of undefined error, it looks like we have a race condition around when the resources get populated and when we try to access them via HUD. I've opened up a separate issue to track that here: Glimpse/Glimpse.Node.Prototype/issues/524.

[philliphoff]

This should be resolved (i.e. worked around, at least) with #528.

[nikmd23]

528 is closed. Can we confirm if this is fixed?

[philliphoff]

The issue as reported is fixed, but there were 2 related issues that have fixes as well, but not all are yet released (as of 0.11.1). I'd wait to close this until verified with 0.11.2.

[focusaurus]

Issue is resolved for me with 0.11.1. Thanks!

[nikmd23]

Thanks for the update @focusaurus!
