Function upsert_json_value 

pub(crate) fn upsert_json_value(
    data: &mut Value,
    value: &str,
    key: &str,
) -> Result<()>

Upserts a value into a JSON object based on a dot-separated key.

This function navigates through a mutable serde_json::Value object using a path-like key. It creates nested JSON objects if they do not exist along the path. The value is inserted at the final key in the path.

Arguments

• data - A mutable reference to the serde_json::Value to be modified.
• value - The string representation of the value to upsert. This string is first parsed as JSON, and if that fails, it’s treated as a plain JSON string.
• key - A dot-separated string representing the path to the location for upserting.
