Hi @pdguru81 - thanks for reaching out.

Can you please provide a minimal reproducible code for us to further review this behavior? I wasn't able to reproduce the issue on my end or find any outstanding issue reports.

This issue seems to be caused by a backwards incompatibility of the recent versions of the sdk clients with older version of the @aws-sdk/core. For us, the issue was caused by having a client-sqs with v3.620 in one layer, and then client-sts with v3.470 in another layer, and the client from the first layer tries to call the @aws-sdk/core from the second layer and throws this error.

The root cause to this issue is likely the mismatched dependencies installed. Since we haven't heard back for further details, I'm going to close this issue now. Please feel free to open a new issue if you need further assistance.
