Not able to parse int in my data class
See original GitHub issueIn my data calss, I have a field quantity defined as below:
val quantity : Int
in the json it looks like:
"quantity" : 3
When I run the code I got the exception
Caused by: com.beust.klaxon.KlaxonException: Unable to instantiate Line:
Parameter quantity: expected java.lang.Integer but received kotlin.Int (value: 2)
After this i undersstood the problem is with my data type, and the library by default cast the values into java data type, so I change it to java.lang.Integer.
val quantity : Integer
even this dosn’t helped and still I’m facing the same error with java.lang.Integer.
Caused by: com.beust.klaxon.KlaxonException: Unable to instantiate Line:
Parameter quantity: expected java.lang.Integer but received java.lang.Integer (value: 2)
Since in the JSON the type of keys are not defined the library should cast based on the data class variable just like GSON and Jackson library do.

You have to use null safe type, eg. Int?
I have the same issue. I got this error from every type of JSON field.
