无法向SQS FIFO队列发送消息，请求缺少MessageGroupId参数

我尝试使用以下代码片段向SQS FIFO队列发送消息：

Message<String> message = MessageBuilder.withPayload("1234")
          .setHeader("message-group-id", "1")
          .setHeader("message-deduplication-id", "1")
          .build();
Map<String, Object> messageHeaderMap = 
                Map.of("message-group-id", "1",
                       "message-deduplication-id", "1");
queueMessagingTemplate.convertAndSend(new QueueMessageChannel(amazonSQSAsync, queueUrl), message, messageHeaderMap);

为确保稳妥，我同时在Message对象和Map中设置了相关属性，但仍收到如下错误：

org.springframework.messaging.MessageDeliveryException: The request must 
contain the parameter MessageGroupId. (Service: AmazonSQS; Status Code: 400; 
Error Code: MissingParameter; Request ID: 9510767b-3be2-59a8-9fc6-2b6f48c0591c; 
Proxy: null); nested exception is 
com.amazonaws.services.sqs.model.AmazonSQSException: The request must contain 
the parameter MessageGroupId. (Service: AmazonSQS; Status Code: 400; Error 
Code: MissingParameter; Request ID: 9510767b-3be2-59a8-9fc6-2b6f48c0591c; Proxy: 
null)

我完全不清楚该如何解决此问题，恳请各位提供帮助。

编辑

我根据建议重构了代码如下：

Message<String> message = MessageBuilder.withPayload("1234")
          .setHeader("message-group-id", "1")
          .setHeader("message-deduplication-id", "1")
          .setHeader("messageGroupId", "1")
          .setHeader("messageDeduplicationId", "1").build();

Map<String, Object> messageHeaderMap =  Map.of("message-group-id", messageGroupId,
        "MessageGroupId", "1",
        "message-deduplication-id", "1",
        "messageGroupId", "1",
        "messageDeduplicationId", "1");
queueMessagingTemplate.convertAndSend(sqsMessageChannel, message, messageHeaderMap);

但仍然收到完全相同的错误。
