[Python] How to display both application/json and application/octet-stream content types in...

I have an endpoint that can return JSON or a file (xlsx):

class ReportItemSerializer(BaseModel):
id: int
werks: Annotated[WerkSerializerWithNetwork, Field(validation_alias="werk")]
plu: Annotated[str, Field(description="Название PLU")]
start_date: Annotated[date, None, Field(description="Дата начала периода в формате")]
end_date: Annotated[date | None, Field(description="Дата окончания периода")]
anfmenge: Annotated[int | None, Field(des cription="Запас на начало периода")]
endmenge: Annotated[int | None, Field(description="Остаток по PLU в разрезе поставщика на конец периода")]
soll: Annotated[int, None, Field(description="Поступило за период")]
haben: Annotated[
int | None, Field(description="Количество по PLU, которое было возвращено поставщику за указанный период")]
model_config = ConfigDict(from_attributes=True)


class PaginatedReportItemsSerializer(BaseModel):
count: int
results: list[ReportItemSerializer]


@router.get(
"/orders/report",
responses={
200: {
"description": "Return report",
"content": {
"application/json": {
"schema": PaginatedReportItemsSerializer.schema(ref_template="#/components/schemas/{model}")
},
"application/octet-stream": {}
},
},
}
)
async def get_report():
pass

Nested ReportItemSerializer is not being displayed (string is instead displayed).

How can I fix it?
