Hi, your problem is not convex, so there are no reduced costs which triggers the error. We could maybe raise a better error or return only the primal values in optlang if those are available. But non-convex optimization is not supported well in cobrapy at the moment.

That's actually a similar problem to what I already had: #1372 (comment)
I looked into the code and have a general idea on how to tackle this. I think it would be the best to have a default case which is executed if shadow prices and/or reduced costs can't be accessed. This is relatively ease to mitigate, so I will make a PR soon which introduces better error handling.
