I’m facing an issue while running cert-issuer -c conf.ini and I have the following in my ethereum_requirments.txt file:
coincurve==7.1.0
rlp<1
ethereum==2.3.1

Here’s the complete Traceback:

This error saying that you are trying to use a function that is not available on dict. In most cases, you try to use the python split() method on a dict, you get the error “AttributeError: ‘dict’ object has no attribute ‘split’”. Dict in python do not have a split method. split is a method of strings(str.split())
