Document_changed event webhook is not calling

Hi,
I am trying to write a webhook to detect the document in a bucket update and call a external url. I am changing a document from couchbase admin panel but webhook is not triggered.
Please help me. I am new in couchbase.
In console warning:
2020-04-30T20:25:47.076+05:30 [WRN] changeCache: Doc “1586773668656” does not have valid sync data. – db.(*changeCache).DocChanged() at change_cache.go:448

my event_handler json:
{

"log":["REST+","CRUD+","Events","Events+","HTTP+"],

"databases": {

        "db": {

                "server": "http://localhost:8091",

                "username": "xxxxxxxxxx",

                "password": "xxxxxxx",

                    "document_changed": [

                        {

                            "url": "http://localhost:3000/notify",

                            "timeout": 30

                                                             

                        }

                ]

            },

            "allow_conflicts": false,

            "revs_limit": 20

        }

}

}

Try enabling shared-bucket-access. Looks like document was not imported correctly

Thanks, it is working now and I had to restart my pc, I don’t know why it was not working.
