The property ‘__metadata’ does not exist on type ‘SP.List’

Here we are going to create a SharePoint list using Power Automate flow.

• Create an instant cloud flow that triggers manually. Then Add an action ‘Send an HTTP request to SharePoint‘ from action triggers and provide the SharePoint site address.
  • Method- POST
  • Uri- /_api/web/lists
  • Headers-
    • Accept – application/json;odata=verbose
    • content-type – application/json;
  • Body: Add the below JSON code to create a new list using Rest API and dynamically pass the JSON content values for Title, Description, and Base Template.

{
  "__metadata": {
    "type": "SP.List"
  },
  "AllowContentTypes": true,
  "BaseTemplate": 100,
 "ContentTypesEnabled": true,
 "Description": "My list description",
 "Title": "Test"
}

Save and run the flow by selecting the run flow option and it throws an error like below, and the SharePoint List is not created in the SharePoint site.

• Now we are getting an error: The property ‘__metadata’ does not exist on type ‘SP.List’. we will see how to fix it.
• It is because when we set the ContentType request header in Send an HTTP request to SharePoint action, instead of “application/json” we have to pass the values as “application/json;odata=verbose” as highlighted below:

The correct content type is

"application/json;odata=verbose"

Save and run the flow by selecting the run flow option, we can see our flow ran successfully and the SharePoint List was also created on the SharePoint site.
