Hi, I'd like to ask a question of flyte type. I am using custom class module, Kirin with flyte. Flyte does not return any type error before when I run sample code of flyte, but I have no idea why flyte make this error.

ValueError: Type <class 'kirin.api.Kirin'> not supported currently in Flytekit. Please register a new transformer

The above exception was the direct cause of the following exception:

would you give any idea to solve this happening?

Hi @gifted-house-14547 can you check these docs https://docs.flyte.org/projects/flytekit/en/latest/design/authoring.html#design-authoring and sections around typetransformers that would make flyte understand the new types that you want to use

@gifted-house-14547 Could you share code snippet? Flytekit should be able to convert unknown type to pickle. https://docs.flyte.org/projects/cookbook/en/latest/auto/core/type_system/flyte_pickle.html#sphx-glr-auto-core-type-system-flyte-pickle-py

Ya this should default to using pickle

I have tried to use

@dataclass

&

@dataclass_json

on the custom class, and unified the return type with this custom class, then it worked.

thank you for updating this
