botocore.errorfactory.MalformedPolicyDocumentException: An error occurred (MalformedPolicyDocument) when calling the CreatePolicy operation: Syntax errors in policy.

Answer 1

整个策略有太多的警告，即使我能够通过控制台创建它。

例如，aws:currentTime应该是如下所示的某种思考：

                "DateGreaterThan": {"aws:CurrentTime": "2020-04-01T00:00:00Z"},
                "DateLessThan": {"aws:CurrentTime": "2020-06-30T23:59:59Z"}

ec2:instanceType条件没有指定相应的条件值。
