Place api gives with internal error

Question

The operation couldn’t be completed. An internal error occurred in the Places API library. If you believe this error represents a bug, please file a report using the instructions on our community and support page (https://developers.google.com/places/support).

I am getting this error. I was able to work for some hours . Nothing changed in code. After some time i am getting the above error for every request

Some code in iOS i used

- (BOOL)textField:(UITextField *)textField shouldChangeCharactersInRange:(NSRange)range replacementString:(NSString *)string {
    NSString *text = [textField text];
    text = [text stringByReplacingCharactersInRange:range withString:string];
    if (text.length>0) {
        footerView.hidden = NO;
        [footerView startAnimating];
    }else {
        [self removeDropDown];
        return YES;
    }
    [_fetcher sourceTextHasChanged:text];
    return YES;
}

Delegate methods

- (void)didAutocompleteWithPredictions:(NSArray *)predictions {
    resultsArray = [[NSMutableArray alloc]init];
    NSMutableArray *titlesArray = [[NSMutableArray alloc]init];
    for (GMSAutocompletePrediction *prediction in predictions) {
        [titlesArray addObject:[prediction.attributedPrimaryText string]];
        [resultsArray addObject:prediction];
    }

    if (self.searchTextField.text.length>0) {
        if (dropDown == nil) {
            dropDown = [[PTDropDownView alloc] showDropDown:self.searchParentView withheight:autoCompleteViewMaxHeight withItems:titlesArray animationDirection:DirectionDown];
            dropDown.delegate = self;
        } else {
            dropDown.itemsArray = titlesArray;
            [dropDown.tableView reloadData];
        }
        dropDown.backgroundColor = [UIColor colorWithRed:0.0 green:0.0 blue:0.0 alpha:0.4];
        [self adjustDropDownFrame];

        [footerView stopAnimating];
    }

    NSLog(@"fetched count = %d",resultsArray.count);

}

- (void)didFailAutocompleteWithError:(NSError *)error {

        NSLog(@"%@",[NSString stringWithFormat:@"%@", error.localizedDescription]);
    [self removeDropDown];
}

Answer 1

we need to provide API_Key for GSMPlacesClient like GMSPlacesClient.provideAPIKey("Your_APIKey") just like we go it for GMSServices

Answer 2

I was able to resolve the error by ensuring that an empty query was not being sent. Note that I am not using the GMSAutoCompleteFetcher() wrapper and instead using a shared GMSPlacesClient to fetch predictions.

Swift 2:

    func autocompleteQuery(withQuery query: String) {
    if !query.isEmpty {
        placesClient.autocompleteQuery(query, bounds: self.bounds, filter: .None) { results, error in
            guard error == nil else {
                print("Autocomplete error \(error)")
                return
            }
            self.predictions = results!
            dispatch_async(dispatch_get_main_queue()) { self.autocompleteResultsTableView.reloadData() }
        }
    }
}

After some days i come to know that it will give the results for certain number of searches per a day. I got the above error in one day. In next day without code change that is working.
