Failed to load Cognito resources #6

Closed mehran22000 closed 4 years ago

mehran22000 commented 4 years ago

I just followed the instructions given in "https://docs.aws.amazon.com/solutions/latest/serverless-bot-framework/deployment.html". When I try this in a chrome browser, the bot does not seem to respond and always it returns back with '...'. Could it be a Cognito access problem?

I think the root of this issue back to the train Model script

Hi @mehran22000, thanks for trying out this solution and your question. We are looking into your question and will get back to you on Friday.

aassadza commented 4 years ago

Hi @mehran22000, we have completed the analysis of the issue and a fix has been published. Thanks for raising it and your help in investigating it.

The root cause was a temporary breakage in Underscore (JavaScript library) in its version 1.10.0, which is a dependency in train-model in this solution that got picked up automatically and went undetected.

The temporary breakage in Underscore (JavaScript library) was introduced in its version 1.10.0 on March 30, 2020 and was fixed in its version 1.10.2 on that same day. Here is a link to that issue with more details https://github.com/jashkenas/underscore/issues/2836.

Unfortunately, our solution build picked up the temporary breakage in Underscore dependency and this went undetected until you noticed it. We have addressed the issue by rebuilding the solution today to pick up the fix in Underscore dependency. We are also putting measures in place to avoid picking up broken dependencies and detect such breakages in the future.

Thanks again for deploying the solution and please let us know in case you notice any other issues or have other feedback.
