Intermittent `Cannot read property error of undefined` error on start bot

[darrenj]

Describe the bug

Intermittently hitting this error when click start Bot. Clicking start bot right away results in things working. Then later on, no pattern it will spuriously throw this unhelpful error.

Shiproom - intermittent issue. working to get a consistent repro

[boydc2014]

Some might be related, there is a known issue in bf-lu that the error message is "undefined", and @cosmicshuai fixed it in bf-cli. Here is the PR picking up that change in composer #7399.

I tried to repro this issue by calling luis build several times concurrently. And in my branch of fixing the undefined error, it can displayed the correct error msg from luis portal.

Shiproom - still looking for a reliable repro to understand, moving out to R14

We believe #7399 has addressed this. Closing for now. @darrenj please re-open if you continue to see this.
