To format the answer as an HTML content in a div without body, h1, and html tags, you can use the following code:

“Top-level object must be a mapping” is an error message that commonly occurs when working with YAML or JSON data formats.
In YAML, a mapping refers to a set of key-value pairs represented by indentation and colon (:). It serves as a way to organize data hierarchically. For example:
user:
name: John Doe
age: 30
In this example, “user” is the top-level mapping, and “name” and “age” are its keys.
However, if you receive the error “Top-level object must be a mapping”, it means that your YAML or JSON data does not start with a mapping. Instead, it might start with a scalar value (e.g., a single string or number) or an array (e.g., a list of items).
To resolve this error, you need to make sure that your top-level object is a mapping. Here’s an example of valid YAML with a mapping as the top-level object:
name: John Doe
age: 30
In this case, “name” and “age” are the keys of the top-level mapping.
Make sure to check if your data format follows the correct syntax and structure defined by the YAML or JSON specification. This will help you avoid the “Top-level object must be a mapping” error.

In the above code, the content is wrapped within a div tag without the body, h1, and html tags as specified. The error message is explained in detail, accompanied by examples and explanations of YAML mappings.
