Warning illegal string offset (Solution)

Hi there

I get this warning messages:
Warning: Illegal string offset ‘formId’ in C:\xampp\htdocs\wp-content\plugins\repeater-add-on-for-gravity-forms\class-gf-field-repeater.php on line 287

Warning: Illegal string offset ‘children’ in C:\xampp\htdocs\wp-content\plugins\repeater-add-on-for-gravity-forms\class-gf-field-repeater.php on line 291

This is because the code it is trying to use a string like an array so my solution was add this line in 287:
$value = array();

this is the piece of code you must change:

			if (empty($value)) {
				$value = array();
				$value['formId'] = $form_id;
				if (!empty($repeater_start)) { $value['start'] = $repeater_start; }
				if (!empty($repeater_min)) { $value['min'] = $repeater_min; }
				if (!empty($repeater_max)) { $value['max'] = $repeater_max; }
				if (!empty($repeater_children)) { $value['children'] = $repeater_children; }

				$value = json_encode($value);
			}

Hope this help
