kedro-fast-api works?
I am testing it, for this I have created a new project based on the starter pandas-iris.
I run the "kedro run" and "kedro run --pipeline=api_pipeline" and everything is apparently fine.
now i start the api:

when i fill the inputs in the api i get this error:
This is the definition of the catalog and the catalog of the "api_pipeline"
this is the node and pipeline from "api_pipeline"
I check in "kedro jupyter lab" that it works, I'm replicating what the api is doing:
This is the error message that doesn't look good in the image:
