Describe the bug

After migrating our v2 SDK clients to v3, we're seeing this specific error sporadically but frequently when sending a command:

Cannot set property message of  which has only a getter
 
TypeError: Cannot set property message of  which has only a getter
    at message (webpack://.../node_modules/@smithy/middleware-serde/dist-es/deserializerMiddleware.js:16:18)
    at output (webpack://.../node_modules/@smithy/core/dist-es/middleware-http-signing/httpSigningMiddleware.js:18:10)
    at null (webpack://.../node_modules/@smithy/middleware-retry/dist-es/retryMiddleware.js:27:32)

All @AWS-SDK dependencies in package.json are pinned to 3.716.0. We also explicitly declare @smithy/[email protected] for the ServiceException type.

Based on the stacktrace, this appears to be a deserialization error. But I'm curious if there may be second problem when @smithy/middleware-serde tries appending a hint to the original error message, which appears to be where the error in the stacktrace above originates.
