The behaviour is as followed:

1. Starting the hop-web container
2. creating/opening a pipeline
3. creating a JavaScript component
4. editing the component from 3. -> it works fine
5. reloading the page in the browser or waiting for time out of the session
6. trying to edit JavaScript component: it fails to open the Edit-Dialog with following error:

I've tested it in three different environments:

1. Kubernetes environment used by @poonam541: the error can be reproduced
2. Kubernetes from DigitalOcean: the error can't be reproduced
3. Container running on Ubuntu Linux access from a Windows-Client (Chrome) in the same Network: the error can be reproduced In cases 1. and 2. the Hop-Web was accessed from the same Windows PC

I've tested it with Hop-Web versions 2.6.0, 2.7.0, 2.8.0, and latest snapshot
