verify_wrapper.py has a bug related to headers

[adriangabrieloros]

the verify wrapper expects the 'custom_provider_headers' field:

headers = kwargs.get('custom_provider_headers', [])

but from the verify.py the following is sent:
'custom_provider_header': list(headers),

So it expects headers, not header.
I removed the extra 's' locally, and it works.

Can I just check you actually mean verifier.py not cli/verify.py?

I think you're correct and it's a bug where I changed it in one place (the verifier class was the new addition so makes sense to fix it there)

[adriangabrieloros]

Yes, i confirm that.
