Issue with browse node lookup? (e.g., amazon.browse_node_lookup(BrowseNodeId=1036682)

[williamshayes]

Apologies if I'm making a noob error, but I can't seem to get browse node to work correctly. I'm a version ahead so that might be the issue but as near as I can tell in my own debugging the call to browse node returns a correct response group and I can see the expected information but in lxml it looks like when the parser is applied something goes awry and I can't figure it out. Here's as much as I can provide.

SAMPLE PROGRAM (I've added the error shown as comments after the call)

from amazon.api import AmazonAPI
AMAZON_ACCESS_KEY = "***"
AMAZON_SECRET_KEY = "***"
AMAZON_ASSOC_TAG = "***"
amazon = AmazonAPI(AMAZON_ACCESS_KEY, AMAZON_SECRET_KEY, AMAZON_ASSOC_TAG)

bn = amazon.browse_node_lookup(BrowseNodeId=1036682)
print(bn.name)

print(bn.name)

Let me know if I've missed something and apologies if it is something basic. Also, I do see that this is a version ahead of what was certified. Your help would be appreciated if possible.

Thanks,

The XML returned from the request for Browse node id 1036682 includes the error message 1036682 is not a valid value for BrowseNodeId. Please change this value and retry your request. There should probably be a more transparent error in the python code here.

2619526011 is a valid browse node. amazon.browse_node_lookup returns a list of browse nodes, so bn[0].name will return the name you're looking for.
