Amazon Simple Product API error when looking up product

Question

from amazon.api import AmazonAPI

AMAZON_ACCESS_KEY = "A******************A"
AMAZON_SECRET_KEY = "7***********************E"
AMAZON_ASSOC_TAG = "j*****-20"

amazon = AmazonAPI(AMAZON_ACCESS_KEY, AMAZON_SECRET_KEY, AMAZON_ASSOC_TAG, region='US')
print(amazon)
#product = amazon.lookup(ItemId='B002RL8FBQ')

When I run the code above it works fine and I get this output from the print function: <amazon.api.AmazonAPI object at 0x7fb6e59f7b38>

So everything is working fine with my access key, secret key, and associate tag.

However, if I un-comment the last line #product = amazon.lookup(ItemId='B00EOE0WKQ') then I get this error traceback:

Traceback (most recent call last):

I have followed the instruction from the official github for this https://github.com/yoavaviram/python-amazon-simple-product-api and the code I am using you will see I have used from the "Usage" subheading on the github page, thus I am not sure what's going wrong.

For added info, I am using a virtual environment and to show that I have the correct packages installed here is my out put of pip freeze:

(myvenv) darren@my_comp:~/Python_projects/amazon_wp$ pip3 freeze
bottlenose==0.6.3
lxml==3.6.0
python-amazon-simple-product-api==2.1.0
python-dateutil==2.5.3
six==1.10.0

Also, I have tried several different asin numbers of valid products and I get the same error message.

I am using python 3.4 on ubuntu 14.04

I think, problem is with region. Please select valid value from here. Explanation can be that AWS can validate your credentials, but when it comes to "real" call it fails, since 'US' is not valid region...
