Quote price is zero but equity is active

Anyone know what is causing this.

This morning, I tried fetching the quote for KSA 5 min after market open. I could see on various tickers that the ETF was being actively traded but when I get_last_quote, what is returned looks like:

Quote({ ‘askexchange’: 15,
‘askprice’: 0,
‘asksize’: 0,
‘bidexchange’: 15,
‘bidprice’: 0,
‘bidsize’: 0,
‘timestamp’: 1636727702424488673})

Is this a issue with a specific exchange?
