Error in sequence DDS response

I'm running into and issue where Pydap is erroring out in the middle of generating the DDS (data structure description).

$ curl 'http://docker-prod01.pcic.uvic.ca:30223/pcds/lister/raw/EC_raw/1145M29.rsql.dds'
Dataset {
    Sequence {
        Float64 wind_direction;
        Float64 air_temperature;
        Float64 wind_gust_speed;
        Float64 tendency_amount;
        Float64 wind_speed;
        Float64 mean_sea_level;
        Float64 dew_point;
        Float64 snow_amount;
        Float64 air_temperature_yesterday_high;
        Float64 relative_humidity;
curl: (18) transfer closed with outstanding read data remaining

On the server side we see:

This is preventing any type of usage from client libraries, so it'd be good to get it confirmed and fixed.
