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

In this Power Automate tutorial, we will see how to fix the 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.’.

Recently, while creating a SharePoint list using Rest API in Power Automate, we came across an error ‘an entry without a type name was found, but no expected type was specified’.

This error states that it expects the "__metadata" property that include information about the data type and entity type name.

Below you can refer to the error we got.

So in this Power Automate tutorial, we will solve this error ‘an entry without a type name was found, but no expected type was specified’.

Error: an entry without a type name was found, but no expected type was specified in Power Automate

Here I have created an Instant cloud flow, which will trigger Manually, and then it will do a rest API call to create a SharePoint list.

Below you can refer to my flow

While doing the rest API calls using the ‘Send an HTTP request to Sharepoint’ action, we are providing the below information

• Site address: Provide the SharePoint site address
• Method: Select the method as Post
• Uri: Provide the URI as ‘_api/web/Lists/’
• Headers: provide the header as below

{
  "content-type": "application/json;odata=verbose",
  "accept": "application/json;odata=verbose"
}

• Body: provide the body as

{'parameters':
{
"__metadata":{"type":"SP.List"},
"BaseTemplate": 100,
"Title": "Flow Employees",
"Description": "Employees Details List"
}
}

Now if I run the flow, I get an error ‘an entry without a type name was found, but no expected type was specified’

In the next section, we will see how we can fix the error ‘ an entry without a type name was found, but no expected type was specified in Power Automate.

Solution: an entry without a type name was found, but no expected type was specified in Power Automate

Here first let’s understand the error ‘an entry without a type name was found, but no expected type was specified’ in Power Automate.

If you look closely at the body of the Send an HTTP request to SharePoint action, we specified the body as follows:

{'parameters':
{
"__metadata":{"type":"SP.List"},
"BaseTemplate": 100,
"Title": "Flow Employees",
"Description": "Employees Details List"
}
}

Here the parameter properties we have provided are not required to create a Sharepoint list. To resolve this error, we need to provide the body as below:

{
    "__metadata": { "type": "SP.List" },
    "BaseTemplate": 100,
    "Title": "Flow Employees",
    "Description": "Employees Details List"
}

Now if you run the flow, it will run successfully and create a SharePoint list using Power Automate.
