Hi Farrukh, In the past couple of days, we faced with built issues on the Metron UI cause of a dependency removed from npm by security reasons. While I investigated the issue I had similar error messages as you did. Therefore I think you were might be impacted by the same issue. The thing could impact/broke the build both local or on a managed environment like EC2. I suggest to check out the latest master from apache/metron and try to fire up that on your local machine or deploy it EC2 (if it's there is a way).
In the following PR you could find some more details about the issue: https://github.com/apache/metron/pull/1285 Hope it helps! Regards, Tibor
