Server Response Not matching model (no records) in Swift

Question

sorry if the question is vague but I am trying to be as expressive as possible.

I have the following model:

struct Posts: Codable, Identifiable {
    let id: String
    let title: String
    let content: String
    
    enum CodingKeys: String, CodingKey {
        case id = "_id"
        case title
        case content
    }
}

the server response if a post is found would be the same model no issues because the JSON matches the model .

but if the server returns an error post not found, this would be the response JSON:

{
"error": "No records found"
}

I receive the following when this happens:

keyNotFound(CodingKeys(stringValue: "id", intValue: nil), Swift.DecodingError.Context(codingPath: [], debugDescription: "No value associated with key CodingKeys(stringValue: "id", intValue: nil) ("id").", underlyingError: nil))

what would be the best approach to handle this issue?

UPDATE:

Thank you jnpdx!

So, I did a ErrorResponse Struct, and it did catch the error response like so:

struct ErrorResponse: Codable {
    let error: String
    
    enum CodingKeys: String, CodingKey {
        case error
    }
}

So in my APIServices file, how do I handle this?

// this is what gets the Post data

let decodedData = try JSONDecoder().decode(Post?.self, from: data)

//Do I need another JSONDecoder to also catch the error below the above line like this?

let decodedDataError = try JSONDecoder().decode(ErrorResponse?.self, from: data)
