Hi,

I found that if the user sends the JWT token followed by a comma (,) an IndexError is raised. Is this the expected behaviour? You should be able to reproduce this using the basic example from the docs. It appears that the exception is raised executing s.split()[0] in

flask-jwt-extended/flask_jwt_extended/view_decorators.py

Line 190 in 5bd8b1e

jwt_header = [s for s in field_values if s.split()[0] == header_type]

Regards,

Sounds like a bug to me. Thanks for the report!
