"schema was not found" in functions but in tables it does

[AimbotNooby]

Somehow martin says it can't find the schema "points" for the function function_linestring. But it exists and works for the tables. And also the function definitely exists inside of the schema.
Can you please help we with this error?

Errors:

I also tried auto_publish

  auto_publish:
    from_schemas:
      - points

Errors:

Can you share the function points.convert_points_to_linestring (or better a simplified version which still produces the same result)?
Maybe this is reproducible and our test suite is missig a case ^^

Hey, that's my function:

CREATE OR REPLACE FUNCTION points.convert_points_to_linestring(z integer, x integer, y integer)
RETURNS TABLE (id integer, user_id integer, "time" bigint, altitude double precision, geom geometry(LineString, 4326)) AS $$
BEGIN
  RETURN QUERY
  SELECT id, user_id, "time", altitude, ST_MakeLine(point ORDER BY "time") AS geom
  FROM points.points_table;
END;
$$ LANGUAGE plpgsql;
