Error: Attempt to invoke bookmark for [Function]

###What does this error mean? Error: Attempt to invoke bookmark for [function]

All of a sudden I am getting this error a lot: Error: Attempt to invoke bookmark for [Function]. I do know know what causes the error, the error appears most often when I use hero.say().
Thank you.
-Cheers!

Can you provide some code for which this is happening? We switched to a new interpreter and this error looks like it’s trying to tell you that you’re calling a function which you shouldn’t have access to in some form.

I have included my full code under the “Full Code” spoiler. The particular problem at the momment happens in this funciton:

def histListFn(hist):
    hero.say("histListFn")
    histList = []
    for h in hist:
        histList.append(h)
    hero.say(histList)

The last line, hero.say(histList) returns the error. I do not see any reason for an error, although I could be mistaken. Though I can not remember, I know I have found this error a lot recently and had to stop developing my code. Thank you for takeing a look.

If I recall correctly, the error happens when you try to say an object whose toString method has been overridden by the Python runtime. I believe @rob can provide more details and correct me if I’m wrong.

So, is there anything I can do? Or am I stuck unable to read lists.
Thanks

I believe this is a bug in the engine that the developers should fix.

For the time being, you can use this hack (not really valid Python but it works):

hero.say(histList.join(', '))

Thank you! That seems to fix the problem for now. I hope the development team fixes the bug soon.
