Plugin API: currentuser permission set in manifest but still not able to get user info

manifest.json

{
 ...
  "api": "1.0.0",
  "main": "dist/code.js",
  "ui": "dist/ui.html",
  "editorType": [
    "figma"
  ],
  "permissions": [
    "currentuser"
  ],
  "networkAccess": {
    "allowedDomains": [...],
    "devAllowedDomains": [...]
  }
}

But error is thrown when calling figma.currentUser

"in get_currentUser: "currentuser" permission not specified in manifest.json. Add the following to your manifest.json: "permissions": ["currentuser"]. See https://www.figma.com/plugin-docs/manifest/#permissions for more details."
