    Try downgrading to "@jridgewell/gen-mapping": "^0.3.5" into your depedencies in package.json

    this would work because the distro would be there.

    There is issue with v0.3.6 which doesn’t have dist folder.

    Adding a override to version 0.3.5 in package json to root works here

    "overrides": {
"@jridgewell/gen-mapping": "0.3.5"
}
