requests.get() 在 aws lambda 中抛出异常

Question

我无法从托管在 AWS 上并通过无服务器框架管理的基于 python 的 lambda 函数进行 HTTP 调用。

我试过使用 botocore.vendored 请求模块，但它显示弃用警告并建议使用请求模块本身。

url = V2_URL + '/api/analytics/validate/' + smId
headers = {
    'Content-Type':'application/json',
    'Authorization': token
}

response = requests.get(url, headers=headers)

print('Result: ')
print(response.content)

在 Cloudwatch 中，我看到了这个堆栈跟踪：

[ERROR] UnboundLocalError: local variable 'response' referenced before assignment

正如@blhsing 和@Mark A 指出的那样，@serverless/enterprise-plugin 包的 3.1.1 版中存在一个错误。将其升级到版本 3.1.2 为我解决了这个问题。我所要做的就是 npm i -g serverless 它会自行处理。
