characterization_previous_not_revertible

The recorded previous tipo_compra is not one this API can set.

What to do

The SII's register held a value outside our taxonomy. Choose one explicitly with POST /v1/tax/purchases/\{id\}/characterize.

The envelope

{
  "error": {
    "type": "unprocessable_error",
    "code": "characterization_previous_not_revertible",
    "message": "…",
    "hint": "The SII's register held a value outside our taxonomy. Choose one explicitly with `POST /v1/tax/purchases/{id}/characterize`.",
    "retriable": false,
    "doc_url": "https://docs.facturia.cl/errors/characterization_previous_not_revertible",
    "request_id": "req_01K2R7Q9M4T2VB"
  }
}

Program against code, never against message — the prose can be rewritten, the code cannot (§5.8).

hint and retriable arrive in the response with these exact values: they are a function of code and come from the same dictionary GET /v1/error_codes serves, so the envelope and the dictionary cannot disagree. Both are English on the wire by design — one registry, one language. More in The error envelope.
