I get the following error on the server side:

proto defintion

service ReplyGenerator {
	rpc Reply(GenerateRequest) returns (stream StreamReply) {}
}

message GenerateRequest {
	repeated Message messages = 2;
}

Calling it like this from client:

async for res in service.teamlead_reply(guided_chat.GenerateRequest(messages=[])):

Compilation was done with:

PROTO_DIR=protos
GEN_DIR=generated
protofiles=$(find "${PROTO_DIR}" -name "*.proto")
python -m grpc_tools.protoc -I "${PROTO_DIR}" --python_betterproto_opt=pydantic_dataclasses --python_betterproto_out="${GEN_DIR}" ${protofiles}

Still an issue.
