unknown operator: $search pipeline mongodb stitch

Question

I am trying to run a query using text operator by the new MongoDB feature stitch. I have already tried a few options, but the call responds with the following message:

unknown operator: $search

How can I resolve this error?

I also have the text index created.

{
    "v" : 2,
    "key" : {
        "_fts" : "text",
        "_ftsx" : 1
    },
    "name" : "script_text_description_text",
    "ns" : "test.scripts",
    "weights" : {
        "description" : 1,
        "script" : 1
    },
    "default_language" : "english",
    "language_override" : "language",
    "textIndexVersion" : 3
}

Attempt #1:

client.executePipeline([{
    "service": "mongodb-atlas",
    "action": "aggregate",
    "args": {
        "database": "test",
        "collection": "scripts",
        "pipeline": [{
                $match: {
                    $text: {
                        $search: "docker"
                    }
                }
            }
        ]
    }
}])

Attempt #2:

db.collection('scripts').find({"$text":{"$search":'docker'}})

Attempt #3:

db.collection('scripts').aggregate([{
    "$match": {
        "$text": {
            "$search": "docker"
        }
    }
}])

UPDATE:

I applied this work around.

import { StitchClientFactory,BSON } from 'mongodb-stitch';

let bsonRegex = new BSON.BSONRegExp(search, 'i')
        // showLoading();
        db.collection('clients').find({owner_id: client.authedId(),name:bsonRegex}).execute().then(docs => {
            funct(docs);
            // hideLoading();
        });

Full-text search in Stitch pipeline aggregate actions is currently unsupported in the Beta version of the Stitch product but we hope to support them when Stitch reaches GA (General Availability).
