Update Event Item with HTTP Request to SharePoint ERROR: "An entry without a type name was found, but no expected type was specified. "

Posted on by Thomas Fialek 27

Hi everyone,

 

I am trying to update an event list item with the PATCH method and an HTTP request to SharePoint. I want to change the "All day event" to true for bank holidays. I couldn't figure out what I am doing wrong. I always receive the following error:

 

An entry without a type name was found, but no expected type was specified. To allow entries without type information, the expected type must also be specified when the model is specified.

 

This is how the HTTP request looks like

Glad for any kind of help 🙂

    Hi @Tomeczek,

     

    It looks like your are missing a leading underscore character in your body value.

     

    However, you can update without the metadata part. Below is an example of a POST request with different headers and a different body value. Let me know if that works for you.

     

    Headers

    {
 "Accept": "application/json;odata=nometadata",
 "Content-Type": "application/json;odata=nometadata",
 "If-Match": "*",
 "X-HTTP-Method": "MERGE"
}

     

    Body

    {
"Title": "All Day Event Test date time",
"EventDate": "@{variables('Date')}",
"fAllDayEvent": true
}
