Hello, I'm getting error `Unexpected JSON token at offset 11023: Expected start of the object '{', but had ':' instead`
`JSON input: .....","type":"BLOGPOST","category":"e054042e-bc50-4743-a6f5-94d9.....`  and I'm not sure why

my content class
```@Entity(tableName = POST_TABLE)
@Serializable
data class Content(
    @PrimaryKey(autoGenerate = false) @SerialName("id") val postId: String,
    val body: String,
    @Transient var categoryId: String? = null,
    val createdOn: LocalDateTime,
    val hasBeenUpdated: Boolean,
    val header: String,
    val postLanguage: String,
    val postSlug: String,
    val postTitle: String,
    val status: String,
    val summary: String,
    val type: String,
    val updatedOn: LocalDateTime,
    val visits: Int,
) {
    @Ignore
    val category: Category?=null
    @Ignore
    var subcategories: List&lt;Subcategory&gt;? = null
}```
and category
```@Entity(tableName = CATEGORY_TABLE)
@Serializable
data class Category(
    @PrimaryKey(autoGenerate = false) @SerialName("id") val categoryId: String,
    val categorySlug: String,
    val categoryTitle: String
)```
I'm not facing an issue with subcategories only the category class

this is the actual json in postman
```"createdOn": "2022-02-06T16:17:08.16067","updatedOn": "2022-02-06T16:17:08.16067",
"status": "PUBLISHED",
"type": "BLOGPOST",
"category": {
   "id": "08e5788d-bc26-45a4-88fc-918ec5f7d8e9",
    "categoryTitle": "Meta",
     "categorySlug": "meta"
            },
"subcategories": [],```

your exception shows `"category":"`, not `"category": {` as in your example

right, i don't understand why it's reading it like that when in postman it's correct

well try intercepting the request to see what you're actually getting

I have been trying to do that and can't figure it out :sweat_smile: I'm kinda new. I'll figure out how to intercept it and come back with the actual problem I guess. Thanks for answering!

it may be correct in one part of your input but not another? at least you should find where the substring in the exception occurs in your input

so the json is correct but the error happens when it tries so serialize it. What could cause it to come in correct and then go wrong to serialization?

Is it possible that it isn't serializing `category` correctly because it's in the body and not defined in the constructor?
