AttributeError: 'list' object has no attribute 'to_dict'

The error is due to the fact that you are using elements module from fbmessenger and in this element module, there is a Text class, which takes as constructor parameter, a quick_replies. But this quick_replies must be a list of QuickReply object. So you are not converting the information provide for Quick replies from the domain.yml into QuickReply Object. Kind of.

Thanks for raising this issue, @erohmensing will get back to you about it soon.

Hey @RogersNtr, thanks for pointing this out. You seem like you know pretty well what's going on here, would you be interested in contributing a fix? If not, we will of course take care of fixing the bug.

Hey @erohmensing .
I fork the project and fix the bug on my side. I also add some support for PersitentMenu (using Custom from domain.yml), Which were also giving bugs and the modification that I did was in the facebook.py module. I just don't know how to submit it on your side.

[erohmensing]

Hm okay that sounds interesting! If possible it would be good to keep the bug fix PR separate from the new feature support. All you have to do is create a new PR here. Then you can pick out the branch of your fork like so (your fork on the right)

[erohmensing]

Hey @RogersNtr, do regular postback buttons work for you? We're also trying to get down to fixing a problem here

[RogersNtr]

Hey @erohmensing
Yes, regular postback buttons like with "Buttons" key work fine. The ones which bug is the persistent Menu and QuickReplies (even when tried with custom). I just do a pull request with the bug fix.

[akelad]

@RogersNtr have you had a chance to submit a PR yet?

[RogersNtr]

Yes @akelad I just resubmit a PR. I get some stuffs that I need to do for the certificate on my local repo; I did itand now it is pending.
