Looks good to me. I added some nitpick comments to handle.

swh/graphql/resolvers/base_connection.py
121	Using `except Exception as e:` is sufficient here as all caught exceptions derive from it.
132	You could indicate the max page size in error message here.

swh/graphql/resolvers/base_connection.py
121	I added those to be explicit about possible exceptions. This will also let us handle different errors and I think is a preferred practice. Bare exception is caught to be safe :)
