Getting "Unsupported URL Scheme" error when using "esm" option.

[jimsalyer]

When I run lambdaLocal.execute with the "esm" option set to true, I get the following error.

Only URLs with a scheme in: file, data are supported by the default ESM loader. On Windows, absolute paths must be valid file:// URLs. Received protocol 'c:'

Has anybody encountered this and knows a workaround? The only way I could get around it was to actually go into the source (libs/utils.js) and add support for the file protocol, but I think that will only work in Windows.
