TypeError: headers[headerName].trim is not a function at getCanonicalHeaders

[kabo]

Please see aws/aws-sdk-js-v3#5713

Perhaps that should have been filed here, not sure.

Hopefully someone here has any ideas about a fix or workaround :)

Error is coming from this line

smithy-typescript/packages/signature-v4/src/getCanonicalHeaders.ts

Line 31 in 74d1aa5

canonical[canonicalHeaderName] = headers[headerName].trim().replace(/\s+/g, " ");
