根因分析

SQS队列配置了期望特定消息属性的策略或Lambda触发器，但发送的消息不包含这些属性。

English

The SQS queue is configured with a policy or a Lambda trigger that expects specific message attributes, but the sent message does not include them.

解决方案

  1. 发送消息时包含必需的消息属性。使用AWS CLI：
aws sqs send-message --queue-url https://sqs.us-east-1.amazonaws.com/123456789012/my-queue --message-body "Hello" --message-attributes "{\"AttributeName\":{\"DataType\":\"String\",\"StringValue\":\"Value\"}}"
  2. 检查队列策略或Lambda事件源映射以识别必需的属性：
aws sqs get-queue-attributes --queue-url https://sqs.us-east-1.amazonaws.com/123456789012/my-queue --attribute-names Policy
# 审查策略中关于消息属性的条件。
  3. 如果可行，修改Lambda触发器或队列策略使属性变为可选：
# 示例：从策略中移除要求'AttributeName'的条件
aws sqs set-queue-attributes --queue-url https://sqs.us-east-1.amazonaws.com/123456789012/my-queue --attributes Policy='{"Version":"2012-10-17","Statement":[]}'

无效尝试

常见但无效的做法:

  1. Recreate the SQS queue with default settings 90% 失败

    Recreating the queue does not change the requirement for message attributes; the Lambda trigger or policy still expects them.

  2. Send an empty message body 95% 失败

    The error is about missing message attributes, not the body; an empty body does not resolve the attribute requirement.

  3. Increase the message retention period 98% 失败

    Retention period does not affect message contents or attribute validation.
