BadRequestException: Error occurred when updating content property content-appearance-draft

[Deleted user]

I am using REST API of the confluence cloud for creating a new page. Sometimes (not always) I have an error in response

{
    "statusCode": 400,
    "data": {
        "authorized": false,
        "valid": true,
        "errors": [],
        "successful": false
    },
    "message": "com.atlassian.confluence.api.service.exceptions.BadRequestException: Error occurred when updating content property content-appearance-draft. Cannot create new content property, see https://docs.atlassian.com/confluence/REST/latest/#content/{id}/property-create for usage. Property : JsonContentProperty{id='null', key='content-appearance-draft', content=ExpandedReference{idProperties={id=ContentId{id=1432322065}, version=EmptyReference{referentClass=class com.atlassian.confluence.api.model.content.Version}, status=current}, of=some(Content{id='ContentId{id=1432322065}', type=page, title='postman page 04', status=current, space=ExpandedReference{idProperties={key=~117839248}, of=some(Space{key='~117839248', name='null'})}, history=EmptyReference{referentClass=class com.atlassian.confluence.api.model.content.History}, version=EmptyReference{referentClass=class com.atlassian.confluence.api.model.content.Version}, ancestors=[Content{id='ContentId{id=1426130768}', type=null, title='null', status=current, space=EmptyReference{referentClass=class com.atlassian.confluence.api.model.content.Space}, history=EmptyReference{referentClass=class com.atlassian.confluence.api.model.content.History}, version=EmptyReference{referentClass=class com.atlassian.confluence.api.model.content.Version}, ancestors=null (CollapsedList), container=EmptyReference{referentClass=interface com.atlassian.confluence.api.model.content.Container}, childTypes={}}], container=EmptyReference{referentClass=interface com.atlassian.confluence.api.model.content.Container}, childTypes={}})}, version=null} , isSuccessful: false, isAuthorized: false, isValid: false, hasErrors: true, Errors: \"jsonproperty.duplicate.key\""
}

I am using Postman, the request body is like this:

{ "type":"page", 
  "title":"postman page 04", 
  "ancestors":[{"id":123456789}], 
  "space":{"key":"~117839248"},
  "metadata": { "properties": { 
                               "editor" : { 
                                  "key": "editor",  
                                  "value" : "v2" }, 
                               "content-appearance-draft":{ 
                                  "key": "content-appearance-draft",  
                                   "value" : "full-width" }, 
                               "content-appearance-published":{ 
                                   "key": "content-appearance-published",  
                                   "value" : "full-width" } 
                                } 
             }, 
 "body":{  
       "storage":{ 
            "value":"<h2>Title</h2><br/># subtitle (2021-06-10)\n <br/>- <a href=\"http://localhost:8080\">http://localhost:8080</a> text1 <br/> ",  
            "representation":"storage" }}}

Could you help me to understand what is wrong?
