Hi @AkshayDobariya

If you authorised your App, then added a scope later, you will need to reautorise the App to give it permission to use the added scopes.

Is that what happened?

I already reauthorized the app, but I got the same error.

Sorry for the delay @AkshayDobariya

Are you uploading the file using the Forms API or the Engagements API?

This [page about Scopes](https://developers.hubspot.com/docs/api/working-with-oauth#scopes) may help?

Have fun
