Hello Rajeev_Sharma,

What steps did you take to get to this error?
We would need additional context to help you.

I assume you’re on Windows.

Using something like npx cross-env SINGLE_START=modeler npm run dev should run successfully.

I’ve created a PR that fixes this issue: fix: make npm start run on Windows by philippfromme · Pull Request #1422 · bpmn-io/bpmn-js · GitHub

You can expect this to work out of the box with the next release. :+1:
