Exception: argument 2 to map() must support iteration

Code:
# Rebuild oauth handler
auth = tweepy.OAuthHandler(CONSUMER_KEY, CONSUMER_SECRET)
auth.set_request_token(session.rtoken_key, session.rtoken_sec)

# Fetch access token
try:
    auth.get_access_token(request.vars.oauth_verifiler)
except tweepy.TweepError, e:
    return e # here

Could you also paste a trace back for this exception. Thanks.

...I am new to python, and using web2py. I've tried, but don't known how to trace.
Sorry~
Is your gea example able to work?

[joshthecoder]

Remove the try block and it should print out a traceback report on the console.

Ummm, it's my bad. I passed None request_key&secret to auth.set_request_token before get_access_token.
Thanks.
Keep up good works.

Glad you figured out the issue.

I'm having the same problem. As long as I just use one auth object on the terminal everything goes fine, but as soon as I try to rebuild the object on another, it fails. I'm just doing auth.request_token.key and auth.request_token.secret in one terminal, and copying them to the other one to do auth.set_request_token("long value", "another logn value")
