Greetings everyone. I'm attempting to use the the Pydantic plugin and have run into issues when using a Pydantic class as an input to a workflow started remotely in the sandbox. Everything works well running locally, but when containerized and run in the sandbox and error is triggered. I did some initial debugging and it looks like the error is due to an unexpected null in the structure passed to the plugin. To demonstrate the problem, I put together a simple example at: https://github.com/artgramlich/flyte-complex-types-problem showing the issue. I'm not sure if this is an actual issue or I'm just missing something, but happy to open an issue if needed.

can you open an issue please?

Will do. And thanks for the help

thank you, might need to ask around a bit. please bear with us.

For reference I've created the issue: https://github.com/flyteorg/flyte/issues/5236 Thanks again.

thanks, will follow up. trying to understand a bit more of the design of the plugin

I am unable to get pydantic types working as inputs to either a

task

or a

workflow

due to this same error, is this not supported?

cc @high-accountant-32689 was recently upgrading pydantic types - we observed some problems

@freezing-airport-6809 I'm looking to write my own type transformer where pydantic models are passed around as simple JSON-serialized strings. Do you know where I can find a good example of this? Currently reading through the transformers in the flytekit repo

Also @boundless-policeman-47000 please put your notes here - https://github.com/flyteorg/flyte/issues/5318
