I was working on a large scale project and tried to use this NPM but it was just giving this error for which I couldn't find a solution. Can someone help me?

Hey @Sassy-Don30 !
I was facing the same issue :/
With the hint from #1005 I realized that immutable dependency was being overwritten to version 4.x due to my project structure.. And checking draft-js package.json it says "immutable": "~3.7.4"..

so, reverting the version of immutable to meet the requirements of draft-js fix my issue

hope this helps you too
