Message start event error ENGINE-02025

Hello, i am trying send message to camunda

var correlationResult = new MessageApi(client).deliverMessage(
                new CorrelationMessageDto().messageName(messageName).correlationKeys(correlationKeys).processVariables(values));

but i have an error - catch ApiException exception;
Then i am trying send message by postman -

 "type": "ProcessEngineException",
    "message": "ENGINE-02025 Variable 'name2' is not of the expected type 'Collection'."
            .setVariable("name1", requestBody.get1())
            .setVariable("name2", list1)
            .setVariable("name3", list2)

How should i send event?
