The user initiates a PostObject request, but the conditions in the policy form field do not include all form fields (excluding x-tos-signature, file, policy, and x-ignore-* form fields).

Example

Assume the policy form field text is constructed as follows:.

{​
  "conditions": [​
    {"success_action_status": "200"}​
  ],​
  "expiration":"2023-12-28T15:04:05Z"​
}​

If the x-tos-date form field exists in the PostObject request, this error returns.

Solution

Refer to PostObject to construct the request form fields correctly and ensure the policy form field value is valid.
