I'm getting the same on the latest versions of aws sdk and aws-sdk-client-mock.

It seems to be coming from @smithy/types. Not sure how to resolve just yet.

I think I resolved it by making sure all @aws-sdk packages were up to date. I had the one I was working with (@aws-sdk/client-s3) updated but I had another one that was added for a different area of the project that had an older version (@aws-sdk/util-stream-node)

The Client type in the AWS SDK up to v3.363.0 was defined in the @aws-sdk/types package. From v3.363.0, the Client type is in @smithy/types. So having installed v3.362.0 and @smithy/types most likely leads to type conflicts.

Updating all AWS SDK packages to the same version and making sure only one version of @aws-sdk/types or @smithy/types is installed usually solves problems. See README and #197.
