Qdrant client scroll filter does not work

I'm using Qdrant database through its Python client. I need to find entries in the database that have some metadata field set to a certain value (without using vector similarity). I'm trying to do it this way:

from qdrant_client.http import models

condition = models.FieldCondition(key="field_name", match=models.MatchValue(value="some_value"))
scroll_filter = models.Filter(must=[condition])
results = client.scroll(collection_name="my_collection", scroll_filter=scroll_filter)

I know that there are points that have metadata "field_name=some_value", but the response is ([], None) no matter what I try. Is there a way to query the database based on metadata only?

(Note: client.scroll(collection_name="my_collection") indeed returns results, some of them having the required key/value pair in the metadata. It's the filter that doesn't seem to work.)

EDIT: The problem was that the data was originally inserted using LangChain, which puts the metadata object within the payload. That further means that instead of using condition=FieldCondition(key="field_name", ..., one must use condition=FieldCondition(key="metadata.field_name", ....

Nothing seems to be wrong at the first glance. Would you be able to share the output of the client.scroll(collection_name="my_collection") with at least one point matching the criteria? I'd like to verify the structure of the payload.
