An entry without a type name was found, but no expected type was specified error in Microsoft Flow

Recently, I was working with Microsoft flow to create a list using Rest API call using Send an HTTP request to SharePoint Microsoft flow action.

While using Rest API in Send an HTTP request to SharePoint flow action, we need to provide the Uri, Headers, and Body. Here the problem was with the Body whatever I was sending in JSON format.

In the Body I was writing below and it was giving the error.

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

And the error was coming like beow:

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.

To solve the issue, we need to modify the Body parameters like below:

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

Once you add like above in the Body parameter, then the flow will run successfully and it will create the list also.
