Mocking EC2 VPC Endpoint Create

Reporting Bugs

• Guidance on how to reproduce the issue. Ideally, this should be a small code sample that can be run immediately by the maintainers. Failing that, let us know what you're doing, how often it happens, what environment you're using, etc. Be thorough: it prevents us needing to ask further questions.

Setting the response from create_vpc_endpoint to a variable

        vpc_endpoint = ec2_client.create_vpc_endpoint(
            VpcId=vpc["VpcId"],
            ServiceName="com.amazonaws.vpce.us-east-1.ssmmessages",
            RouteTableIds=[route_table["RouteTableId"]],
            SubnetIds=[subnet_one["SubnetId"], subnet_two["SubnetId"]],
            VpcEndpointType="Interface",
        )["VpcEndpoint"]

Return the variable and try to return VPCEndpointID fails.

• Tell us what you expected to happen. When we run your example code, what are we expecting to happen? What does "success" look like for your code?

Return the VPCEndpointID in the ec2.create_vpc_endpoint response. This should return the VPCEndpointID instead of an error as it has not been set.

• Tell us what actually happens. It's not helpful for you to say "it doesn't work" or "it fails". Tell us how it fails: do you get an exception? A hang? How was the actual result different from your expected result?

When trying to return VPCEndpointID it throws an error as the response does not have it set.

• Tell us what version of Moto you're using, and how you installed it. Tell us whether you're using standalone server mode or the Python mocks. If you are using the Python mocks, include the version of boto/boto3/botocore.

If you do not provide all of these things, it will take us much longer to fix your problem.

Hi @sansns, Moto does return that value! It has a lower case 'd' though - VpcEndpointId, instead of the VpcEndpointID that you've mentioned. Could that be the problem?

@bblommers - You are absolutely right, I fat fingered it and it did not work. Thank you for catching that.
