executeMethod(abiItemModel, methodArguments, requestType) {
        let method;

        try {
            method = this.createMethod(abiItemModel, methodArguments, requestType);
        } catch (error) {
            const promiEvent = new PromiEvent();

            method = this.methodFactory.createMethodByRequestType(abiItemModel, this.contract, requestType);
            method.setArguments(methodArguments);

            if (isFunction(method.callback)) {
                method.callback(error, null);
            }

            promiEvent.reject(error);
            promiEvent.emit('error', error);

            return promiEvent;
        }
