Issue with basic example

[lhucinequr]

Hello,
I am using a Boto3 in a project of mine, I was trying to do my testing using moto but then while trying to do the basic test presented in the documentation I am having the following error:
E botocore.exceptions.NoCredentialsError: Unable to locate credentials.
It seems like moto is not mocking anything

The example I used is the following

import boto3
from moto import mock_s3
from mymodule import MyModel
@mock_s3
def test_my_model_save():
    conn = boto3.resource('s3', region_name='us-east-1')
    # We need to create the bucket since this is all in Moto's 'virtual' AWS account
    conn.create_bucket(Bucket='mybucket')
    model_instance = MyModel('steve', 'is awesome')
    model_instance.save()
    body = conn.Object('mybucket', 'steve').get()['Body'].read().decode("utf-8"
    assert body == b'is awesome'

Just a follow up, the same test above works in the following environment

boto==2.49.0
boto3==1.7.84
botocore==1.10.84

But not with latest releases of each of the packages

We have nearly the same exception. I've provided stacktraces below. But they are not very useful as the code around line 612 in botocore/client.py was last changed a few years ago.

The breaking release is botocore 1.11.0.

With empty credentials (omitted part is identical to above):

            error_code = parsed_response.get("Error", {}).get("Code")
            error_class = self.exceptions.from_code(error_code)

I think that you're right, it is the latest version of botocore that breaking moto.
By the way when doing pip install moto here is what is installed by default

boto==2.49.0
boto3==1.8.2
botocore==1.11.2

I will be using an earlier release for the time being.
I can't believe that I spent an entire day for this. took me a long time to realize

Same here:

$ AWS_ACCESS_KEY_ID='1111' AWS_SECRET_ACCESS_KEY='2222' python repro.py 
Traceback (most recent call last):
  File "repro.py", line 12, in <module>
    main()

    result = func(*args, **kwargs)
  File "repro.py", line 8, in main

botocore.exceptions.ClientError: An error occurred (InvalidAccessKeyId) when calling the CreateBucket operation: The AWS Access Key Id you provided does not exist in our records.

$ pip freeze
....
boto==2.49.0
boto3==1.8.2
botocore==1.11.2
moto==1.3.4
....

and repro.py:

import boto3
from moto import mock_s3

@mock_s3
def main():
    s3 = boto3.resource('s3', region_name='eu-central-1')

    s3.create_bucket(Bucket='test1111')


if __name__ == '__main__':
    main()

And no problems with

boto==2.49.0
boto3==1.7.47
botocore==1.10.72
moto==1.3.4

We are also seeing the same issue.

This was working with Boto3 1.7.x

If #509 is merged will a new version be cut?

[ghost]

And this issue seems to be a duplicate of #1793

Closing as a duplicate of #1793
