go json unmarshal structs Go

I'm attempting to set up I'm working with an scenario when trying to unmarshal a JSON response into a struct in Go. The JSON includes embedded structs, and one of the fields is a custom type that doesn't seem to unmarshal correctly. Here's the relevant part of my JSON response: ```json { "user": { "id": 1, "name": "John Doe", "preferences": { "notifications": true, "theme": "dark" } } } ``` And this is the Go struct I've defined: ```go type Preferences struct { Notifications bool `json:"notifications"` Theme string `json:"theme"` } type User struct { ID int `json:"id"` Name string `json:"name"` Preferences Preferences `json:"preferences"` } ``` When I attempt to unmarshal the JSON into my struct using the following code: ```go var user User err := json.Unmarshal([]byte(jsonData), &user) if err != nil { log.Fatalf("behavior unmarshaling JSON: %v", err) } ``` I receive the behavior `json: want to unmarshal object into Go value of type string` but my struct seems to be defined correctly. I suspect it might be related to how I’m trying to access the `Preferences` field, or there could be an scenario with the JSON format itself. I’ve confirmed the JSON is valid using an online validator and I also checked that the field names match between the JSON and my struct. I've tried various approaches, including simplifying the struct and using different types for the `Preferences` field, but nothing seems to work. Can anyone guide to understand why I'm working with this scenario? I’m using Go version 1.19 and the behavior continues regardless of how I adjust the JSON structure or my structs. Thanks in advance for any insights! The stack includes Go and several other technologies. Is there a simpler solution I'm overlooking? I'm working with Go in a Docker container on macOS. How would you solve this? This is my first time working with Go stable. Any pointers in the right direction?
