path{string}error{Error}- Returns: {module.SourceMap}
path is the resolved path for the file for which a corresponding source map
should be fetched.
The error instance should be passed as the second parameter to findSourceMap
in exceptional flows, such as when an overridden
[Error.prepareStackTrace(error, trace)][] is invoked. Modules are not added to
the module cache until they are successfully loaded. In these cases, source maps
are associated with the error instance along with the path.
