Misleading error message - Cannot read property 'byteLength' of undefined
See original GitHub issueDescribe the bug
The exception Cannot read property 'byteLength' of undefined is thrown by a client instance in many cases, but, as pointed out in https://github.com/aws/aws-sdk-js-v3/issues/2411#issuecomment-864127937, the problem might be, that keys in the credentials object are spelled in PascalCase, instead of camelCase.
I just had the same problem, and this was indeed what caused it. What makes it worse is the fact, that in the SDK Reference, lower-case properties marked as readonly, so you would never think to dig in that direction.

Removing the needs-review because we know it requires a better error message. But it’s not blocking customer from making request to AWS services. We will implement a fix soon.
