I think this line is throwing the exception in helper._create_aux_model_doc_list_to_list:

create_model(
                model.__name__,
                __base__=model,
                __validators__=model.__validators__,
                **fields,
            )

Somehow I can't see proper exceptions or stack traces in my Jina flows...

Can you please share a minimal reproducible example of the issue? something that I can run and see the problem right away?

The reason these exceptions are not easily seen is because all these collectiing of schemas from Executors is done asynchronously and these exceptions are not so well reported.

Minimal Reproducible Example showcasing the underlying problem:

from docarray import DocList, BaseDoc
from jina.serve.runtimes.helper import _create_aux_model_doc_list_to_list


class MyTextDoc(BaseDoc):
    text: str


class QuoteFile(BaseDoc):
    texts: DocList[MyTextDoc]


class QuoteFileType(BaseDoc):
    """
        QuoteFileType class.
    """
    id: str = None  # same as name, compatibility reasons for a generic, shared `id` field
    name: str = None
    total_count: int = None
    docs: DocList[QuoteFile] = None
    chunks: DocList[QuoteFile] = None


new_model = _create_aux_model_doc_list_to_list(QuoteFileType)
new_model.schema()

Somehow the new_model has a problem when calling .schema(), there is where the KeyError is raised.

I have a candidate PR to fix #6141

I will try to soon add tests, but u can test in advance if possible

hmm, didn't work quite well; we may need to bring cached_models from the topology graph – with a local cached_models list, it still gives the same error

can you please add the example that is giving the error. Otherwise is very hard to debug.

I have updated the PR, can you try again and provide a minimal reproducible example for us to make sure we add relevant testing scenarios?
