can you help understand what this assertion means in human terms? occurring during pybitshares market buy/sell grapheneapi.exceptions.

RPCError: Assert Exception: _sell_asset->options.whitelist_markets.find(_receive_asset->id) != _sell_asset->options.whitelist_markets.end()

The issuer of the asset has closed down trading for this market

It would be helpful if the exception arguments included the above statement

re: user story

I had botscript algo trading on the dex for several days, then suddenly it stopped working and I was getting this error repeatedly whenever algo was attempting buy/sell ops. I spent 2 days searching for a bug in my code (or pybitshares) that might have caused it, and the error argument given via the RPC call was not very discernible or helpful. Eventually, I found out that trading was disabled on all openledger; ie OPEN.* assets via telegram dev chat room. Hence the blue chip market OPEN.BTC/BTS was no longer whitelisted; randomly it didn't exist; it was a "black swan" event of sorts from my perspective, and there was indeed nothing wrong with my code; I just didn't realize that, in human speak:

The issuer of the asset has closed down trading for this market
