Incompatibility with boto3==1.36 and aiobotocore==2.18.0

[cvjjm]

I initially filed a bug against aiobotocore describing the problem here
aio-libs/aiobotocore#1272 (comment)

From the discussion there it seems like people believe that the problem needs to be fixed moto.
Please have a look because currently moto does not work correctly with boto3==1.36 and aiobotocore==2.18.0.

We only support botocore/boto3 @cvjjm - we don't guarantee compatibility with third-party libraries like aiobotocore.

This comes up every now and then, and the ideal way would probably be for someone in the community to create an aiomoto repo that is compatible with aiobotocore - but it's out of scope for us.

I will openly admit that my understanding of precisely which of these libraries is responsible for what is very limited. But if you look at the stack trace you will see that the error arises when moto (in moto/core/responses.py) calls a function that is part of botocore (in botocore/httpchecksum.py).

Are you saying the problem is that aiobotocore is using moto in an unsupported way?

Looks like there might be a temporary solution here:

IIRC - aiobotocore patches the botocore methods to become async, and changes the signature in the process (changes the return value)
moto doesn't know about this, and just returns the value that is correct according to the original botocore signature
