Source map url comments may be present in code but not always be accessible to fetch. If the request for the sourcemap 404s, it should fallback to an identity mapper.

Any chance we can update Line 183 to include a null check for frame (i.e.if (!frame || !frame.fileName) {)? I haven't been able to track down the why of these errors, except that this error only happens after loading an external, third party JavaScript library.

The parameters being passed into const frame = ErrorStackParser.parse(stackInfo)[stackIndex]; which are causing the error are:

stackInfo = {
  "stack": "Error: stacktrace source",
  "message": "stacktrace source"
}
stackIndex = 1
frame = undefined
