VariantFormatException
class VariantFormatException(message: String, val offset: Long = -1, cause: Throwable? = null) : VariantException
The bytes are not a Variant value this implementation can read.
Raised for a truncated value, an out-of-range offset, a field id that is not in the dictionary, a metadata version beyond this implementation, and an unrecognised primitive type id. The project rule is that unknown data is signalled, never defaulted: an unreadable byte means the file cannot be read by this version, not that the value is absent.
