boto error during ec2 instance deletion

[Abhi]

I am testing ec2 instance deletion with python boto (which was also created
with a python script). The disable_api_termination flag is set to True during
instance creation. Once the instance is created, another script uses the
following snippet to delete the instance:

connection.modify_instance_attribute(i.id, "disable_api_termination",
"False")
connection.terminate_instances(i.id)

but I get the "400 Bad request" error. I saw a similar post, but the thread was
a bit old and no definite solution was suggested (unless I missed something).
I would appreciate any pointers on the same.

Below is the traceback
Traceback (most recent call last):

Not sure what version of boto you are using but according to this:

http://boto.readthedocs.org/en/2.3.0/ref/ec2.html

the attribute is:

disableApiTermination

Thank you, you are right, the attribute should be 'disableApiTermination';
possible cause of the confusion would be the parameter that we set initially -
to run a new instance we enable the flag with
connection.run_instances(....,disable_api_termination=True,....). Regardless,
should have verified with the docs first :)
