Hello guys.
I am using ktor client and I can't find a way to handle response error.

Hey. What do you mean by a response error? If you mean some network error then you can wrap a client’s request call in try/catch block to handle the error.

@Aleksei Tirman [JB] I have introduced the try catch block but I want to know how to parse the error message returned by the API.

Bringing it to context, I wrote the server side code and ensured that if any error occurs, a uniform error object is returned as response:

data class Error(
val status: Boolean = false,
val message: String
)

How do I have access to this object from the catch block?

Secondly, is there no way I can do that in the HttpClient configuration rather than repeating it in every endpoint?

[Aleksei Tirman [JB]]

What you are describing is not a server error so you can just deserialize a response to your data class using the ContentNegotiation plugin.

I have used ContentNegotiation on the serverside, how do I use it with an Android client?
