我在 lambda 上使用 sts 客户端时遇到问题。 当前代码在两天前工作。

const {
  STSClient,
  AssumeRoleCommand,
} = require('@aws-sdk/client-sts')

const stsClient = new STSClient({
  region: process.env.REGION || 'eu-west-1',
})

const params = new AssumeRoleCommand({
  RoleArn: process.env.MARKETPLACE_RESOLVE_CUSTOMER_ROLE_ARN,
  RoleSessionName: `${
    process.env.AWS_LAMBDA_FUNCTION_NAME
  }-${new Date().getTime()}`,
})

const assumedRoleOutput = await stsClient.send(params)

现在它总是抛出如下异常：

我已经在 3.266.0 和 3.224.0 版本的@aws-sdk/client-sts 上试过了

问题是在创建图层时安装了不正确的aws-sdk版本。 我使用 docker 文件安装我的 lambdas 使用的所有依赖项，并使用如下命令：

RUN npm i @aws-sdk/[email protected]
RUN npm i @aws-sdk/[email protected]

所以 sdk 版本之间可能存在不一致？

所以我尝试创建层而不包括 aws sdk 模块（手动删除）并且它有效（sdk 包含在 lambda 执行环境中）

但是我遇到了另一个错误

aws-sdk/client-marketplace-entitlement-service

所以我更改了 Dockerfile 上的命令以安装我想要的最新主要版本，如下所示：

RUN npm i @aws-sdk/client-sts@3
RUN npm i @aws-sdk/client-marketplace-entitlement-service@3

现在可以了！
