StitchError: service not found: 'mongodb-atlas' - mongodb-stitch

Question

I am having a problem getting data in android from atlas mongoDB (stitch):
service not found: 'mongodb-atlas'
StitchError: service not found: 'mongodb-atlas'
{
"arguments": [
{
"database": "vutuduDB",
"collection": "test",
"query": {},
"limit": {
"$numberInt": "0"
},
"project": null,
"sort": null
}
],
"name": "find",
"service": "mongodb-atlas"
}
Also when I tried to create a http service and use the console I got the same problem while running the line:
context.services.get("mongodb-atlas");
Java code:
public class SearchFragment extends Fragment {
Button btnSearch;
private StitchAppClient stitchClient;
private RemoteMongoClient mongoClient;
private RemoteMongoCollection itemsCollection;
#Override
public View onCreateView(#NonNull LayoutInflater inflater, #Nullable ViewGroup container,
#Nullable Bundle savedInstanceState) {
super.onCreateView(inflater, container, savedInstanceState);
View layout = inflater.inflate(R.layout.search_fragment_layout, container, false);
this.stitchClient = Stitch.getDefaultAppClient();
Log.d("stitch", "logging in anonymously");
stitchClient.getAuth().loginWithCredential(new AnonymousCredential()
).continueWithTask(new Continuation<StitchUser, Task<Void>>() {
#Override
public Task<Void> then(#NonNull Task<StitchUser> task) throws Exception {
if (task.isSuccessful()) {
Log.d("stitch", "logged in anonymously as user " + task.getResult());
} else {
Log.e("stitch", "failed to log in anonymously", task.getException());
}
mongoClient = stitchClient.getServiceClient(RemoteMongoClient.factory, "mongodb-atlas");
RemoteMongoDatabase db = mongoClient.getDatabase("vutuduDB");
Log.d("stitch", "GETTING ITEMS");
db.getCollection("test").find().forEach(item -> Log.d("ITEM: ", item.toString()));
return null;
}
});
return layout;
}
}
