KotlinReflectionInternalError: Unresolved class: class java.math.BigDecimal$1 #431
Description
I got this error when I add the mapping "Float" to "java.math.BigDecimal" and has an input type with variable of this Float(will be converted to BigDecimal later).
Input type
input AccountInput {
customerId: ID
amount: Float
}
Error log:

The error happens when it calls nestedValue::class.isCompanion as seen below
And the error will be gone if I remove the amount field from input type.
Would appreciate any help on this.
