How to avoid JsonDataException when backend returns different JSONs on different environemnts.

[usopphammer]

Hello. I'm working on application that uses 2 different backend environments - dev and stage. Both are not stable and a lot of changes are performed every week. As a result it's available to receive different responses for the same request at different environments.

For example I receive differen type of the license field on dev and stage. As a result on stage env I receive the error:
com.squareup.moshi.JsonDataException: Expected a string but was BEGIN_OBJECT at path $.license

data classes that I need to use:

on Dev

@JsonClass(generateAdapter = true)
data class PreparePlaybackResponse(

    @Json(name = "id")
    val id: String,

    @Json(name = "asset")
    val asset: Asset,

    @Json(name = "license")
    val license: License? = null,
) 

on Stage

@JsonClass(generateAdapter = true)
data class PreparePlaybackResponse(

    @Json(name = "id")
    val id: String,

    @Json(name = "asset")
    val asset: Asset,

    @Json(name = "license")
    val license: String? = null,
) 

It's not convenient to manually change the type of the field when a build for a different environment is required, especially that the field can be nullable.
I wonder how to properly manage such situation? Is it feasible somehow to ignore the JsonDataException for some fields and just return a null in this case?
