Cannot import jdl file using jhipster

Question

I'm new to jhipster. I am on jhipster v7.8.1, i can generate an app using the cli questions but when i try importing a jdl file i got the following error:

**ERROR! Class constructor GAstVisitor cannot be invoked without 'new' TypeError: Class constructor GAstVisitor cannot be invoked without 'new' at new DslMethodsCollectorVisitor

This occurs due to a recent bug in the one of JHipster libraries. As a temporary solution you can go to the JHipster installed location and find it's package.json file and override the package causing this error as follows. Then run npm install again.

    "overrides":{
      "[email protected]": {
      "@chevrotain/gast": "10.1.2"
     }
    }

This will prevent the JHipster using latest package of that.
