Question by eshopgoods · Feb 25, 2017 at 02:20 PM · trading apipythongetsellerlist

InvalidHeader exception when using Trading API in python

Hello All,

When I am executing a call to get seller listings I am getting back the following exception:

requests.exceptions.InvalidHeader: Header value None must be of type str or bytes, not

When using other API such as Shopping everything works ok?

Could this be a bug in the SDK? How can this fixed or is there any workaround?
