error: getTrades() returned duplicate results

[ilitirit-za]

When I try to backfill some PoloniEx selectors, I get the error stated in the title.

eg.

root@home:~/zenbot# zenbot backfill poloniex.ZEC-USDT --days 365
poloniex.ZEC-USDT saved 200 trades 365 days left
...........
poloniex.ZEC-USDT saved 5886 trades 364 days left
...........
poloniex.ZEC-USDT saved 7364 trades 363 days left
...........
poloniex.ZEC-USDT saved 10082 trades 362 days left
...........
poloniex.ZEC-USDT saved 3065 trades 361 days left
...........
poloniex.ZEC-USDT saved 1844 trades 360 days left
............
poloniex.ZEC-USDT saved 2466 trades 359 days left
.......
error: getTrades() returned duplicate results
{ product_id: 'ZEC-USDT', to: 1495135649 }
{ product_id: 'ZEC-USDT', to: 1495135649 }

I'm using v4.0.3.

Btw, the -V/--version option doesn't appear to work:

root@home:~/zenbot# zenbot --version

I am also getting this error as today, 29 July 2017.

$ zenbot backfill poloniex.ZEC-ETH --days=90

Also can confirm this:

$ ./zenbot.sh backfill poloniex.ETH-BTC --days 90
skipping 116 hrs of previously collected data
poloniex.ETH-BTC saved 200 trades 86 days left
.
error: getTrades() returned duplicate results
{ product_id: 'ETH-BTC', to: 1501709273 }
{ product_id: 'ETH-BTC', to: 1501709273 }

Any thoughts how to solve?

hi, is there any workaround for this problem? All poloniex pairs are returning the same error now.

I know that this issue is newer than #455, but I think that captures the problem better, closing this one in favor of that one.
