[SalesForce] WebService callout failed

This Error is coming. I am wondering what could be the possible issue. I have given permission to the objects.

Web service callout failed: WebService returned a SOAP Fault:
INSUFFICIENT_ACCESS: use of the Metadata API requires a user with the
ModifyAllData permission faultcode=sf:INSUFFICIENT_ACCESS faultactor=

It looks like you are performing operation with Metadata API.That requires Modify all data permission.

You should check the profile of the user that it has Modify all data permission or not.
