SyntaxError: Could not find export 'fromNodeProviderChain' in module '@aws-sdk/credential-providers'

Despite this package beig included, I get this error when trying to run my code. Installing the package locally as a dev dependency, I get no errors about `fromNodeProviderChain` being missing, and can indeed see the export.

Start by reproducing the import of `fromNodeProviderChain` from `@aws-sdk/credential-providers` in LLRT, then compare the runtime's available exports with the package's local behavior. Trace the module-resolution or compatibility entry point involved; done means the reported import runs without the missing-export error.
