Did anyone run into error=place_order failed: PolyApiException[status_code=400, error_message={'error': 'not enough balance / allowance'}] when doing limit sell? Buying works fine for me, but limit sell does not work.

Happens to me too most of the times when doing sells (not just limit sell). My setup is an EOA.

Mine also EOA, does anyone know how to fix/workaround it? My sells only work once for so many that’ve failed.
