Hi folks, i am getting this error when i try to create a client based on a wsdl file with Zeep. Can you guys help me out here? I never had worked with soap web services before.

Also running into this issue and looking into it myself

I have managed to track down the bug to being in lxml rather than zeep. it seems my version of lxml is outdated, and hence throwing a StopIteration exception, which is causing find() to return None.

@luanfonceca What is your lxml version?

Can you give master a try?

@mvantellingen : I was able to reproduce the bug with the latest stable release (2.3.0). I gave a try with master (6dce326), I can confirm it's fixed.

@luanfonceca I just realised there was an error in the .wsdl from my side, which gave the error (soap12 tags specified in soap binding). so it may be that
