Uncaught TypeError: decorator is not a function

[crow-rojas]

¡Hola! Me encontraba jugando con un proyecto personal hecho en AdonisJS 6 y al momento de importar la librería me da el siguiente error por consola:

const { Fintoc } = await import("fintoc");

### Prints
Uncaught TypeError: decorator is not a function
    at DecorateProperty (/Users/crow/crovise-backend/node_modules/reflect-metadata/Reflect.js:561:33)
    at Reflect.decorate (/Users/crow/crovise-backend/node_modules/reflect-metadata/Reflect.js:136:24)
    at __decorate (/Users/crow/crovise-backend/node_modules/fintoc/build/main/lib/mixins/resourceMixin.js:4:92)

Si corro el servidor y hago una request a uno de mis endpoints me da algo parecido:

[03:11:57.099] ERROR (47005): decorator is not a function

He intentado reinstalar paquetes, cambiar versión de Node, reinstalar npm desde 0 y nada.... saben a qué se podría deber esto? Gracias!
