Google Cloud MissingSecurityHeader error - authentication

Question

While there is a thread about this problem on Google's FAQ, it seems like there are only two answers that have satisfied other users. I'm certain there is no proxy on my network and I'm pretty sure I've configured boto as I see credentials in the request.
Here's the capture from gsutil:

Answer 1

It looks like you might not have a default_project_id specified in your .boto file.
It should look something like this:
[GSUtil]
default_project_id = 1234567890
Alternatively, you can pass the -p option to the gsutil mb command to manually specify a project. From the gsutil mb documentation:
-p proj_id Specifies the project ID under which to create the bucket.
