accounts/market_pairs returns empty list

[dongofresh]

def market_pairs(p3cw):
    error, data = p3cw.request(
        entity='accounts',
        action='market_pairs',
        action_id=str(########)
    )
    if error == {}:
        return data
    else:
        raise(Exception(error['msg']))

market_pairs(p3cw)

This returns an empty list each time.

I tried it with several exchanges, both with "id" and "market_code." Other calls like "market_list" or "running_bots" work fine. What am I missing?

Thank you for your work! Best regards Yan
