Any help will be appreciated.

**Is there anything special in your setup?** For example, are you using the Logstash or Kafka outputs? Are you using a load balancer in front of the APM Servers? Have you changed index pattern, generated custom templates, changed agent configuration etc. - **NO**

Hi Kumar,

We were allowing the users to run the transpilation step in the previous versions.

This issue is already handled in the current release, Please update the your `@elastic/apm-rum` to `>= 4.5.0` which would fix the above issue.

Link to changelog - [https://github.com/elastic/apm-agent-rum-js/blob/master/CHANGELOG.md#450-2019-09-30](https://github.com/elastic/apm-agent-rum-js/blob/master/CHANGELOG.md#450-2019-09-30)

Thanks,  
Vignesh
