Two fields with the same type are conflicted with KeyError in pydantic #6140
Description
Describe the bug
I have a type that looks like this:
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] = NoneThis was working fine until v3.23.3, see PR: #6138
With 3.23.3, we are now getting this error while initializing the gateway:
DEBUG gateway/rep-0@81761 gRPC call to hnsw for
EndpointDiscovery errored, with error <AioRpcError of
RPC that terminated with:
status = StatusCode.UNKNOWN
details = "Unexpected <class 'KeyError'>:
<class 'pydantic.main.ImageDocument'>"
debug_error_string = "UNKNOWN:Error received
from peer
{created_time:"2024-02-16T13:28:39.399741-05:00",
grpc_status:2, grpc_message:"Unexpected <class
\'KeyError\'>: <class
\'pydantic.main.ImageDocument\'>"}"
> and for the 2th time. Describe how you solve it
The issue disappears if I remove one of the DocList[QuoteFile] fields (docs or chunks – chunks is there for backward compatibility in one of our use cases).
Environment
jina==3.23.3
docarray==latest upstream with our own fork (i don't think any of our changes are related to this issue)
