The Condition setting in the bucket policy is invalid. The valid Condition configuration should be a Map type, where the Map's key must be a string, and the value must be another Map (with string keys and values that are either strings or lists of strings).

Example

The Condition setting in your bucket policy configuration is invalid.

PUT /?policy HTTP/1.1​
Host: <Bucket name>.<TOS endpoint>​
Date: Fri, 30 Jul 2021 13:59:18 GMT​
Authorization: authorization xxx​
​
{​
    "Version": "2012-10-17",​
    "Statement": [​
        {​
            "Sid": "1",​
            "Effect": "Allow",​
            "Action": ["tos:*"],​
            "Principal": "*",​
            "Resource": ["trn:tos:::bucketname/*"],​
            "Condition": {"abc":123}​
        }        ​
    ]​
}​

Solution

Refer to Bucket Policy Templates and Parameter Descriptions to correctly construct the bucket policy and ensure the Condition setting is valid.
