Bidcycle not working - Futgui is bidding but not clearing the watchlist and not offering the won players

[Fotospecht]

I have an account that behaves strange and the Bidcycle is not working correctly.

This account has different personas, but futgui is picking up the correct persona so I expected it would work fine.

Futgui is watching players and also bidding with this account, but the Futgui log window does not display these events, only the "Updating prices" event can be seen. Also the top right list of players is not populated.

In the web app I can see that the watched players are not removed from the watchlist and the won players are not listed.

I can see the error below in the console:

I found that this problem is not related to the account,
instead the error apperas because some of the players are not working.
I could reproduce this problem on another account.

Zuculini 76
