# `Backplane.Schema.JSONSchema.Encoder.UnsupportedTypeError`

Raised when JSON Schema encoding uses `on_unsupported: :raise` and encounters
a Backplane.Schema schema node that cannot be represented statically.

The exception's `:type` field contains the unsupported node and `:reason`
describes why it could not be encoded.
