AttributeError on invoking lambda

Hi, we're testing out the lambda submission feature of HSDS and we're getting 500 errors on our read requests. I checked the SN logs and confirmed that it's trying to invoke the lambda but is running into the following AttributeError. A quick search for the error suggests that it may be related to aiobotocore?
