not working with IE11? Cannot parse given Error object

In IE11 I get this error: Cannot parse given Error object

window.onerror = (message, file, line, column, errorObject) =>{
    StackTrace.fromError(errorObject).then(callback).catch(e => console.log(e));
}

the error that is triggered seems to be a security error that happens when a new WebSocket is created. SCRIPT5022: SecurityError

same exact story here

window.onerror = function(msg, file, line, col, error) {
  StackTrace.fromError(error).then(callback).catch(errback);
}
var errback = function(err) { console.log('here '+ err.message);
console.log(new Error("from onerror").stack);
};
var callback = function(stackframes) {
    var stringifiedStack = stackframes.map(function(sf) {
      return sf.toString();
    }).join('\n');  };

Hi,

I’m not using stacktracejs “as is”, just error-stack-parser, and had a “Cannot parse given Error object” issue with IE11 as well.

When an error object is created in IE it doesn’t contain the necessary “stack” field at all, an Error needs to have been thrown for it to be defined in the resulting exception.

let error = new Error("getStack");
console.log(error);
if (detectIE()) { // https://stackoverflow.com/a/21712356
    try {
        throw error;
    } catch (e) {
        error = e;
    }
}
console.log(error);
const stackFrames = ErrorStackParser.parse(error); // replace by StackTrace.fromError(error) ?

Console output:

[object Error]{description: "getStack", message: "getStack", name: "Error"}
[object Error]{description: "getStack", message: "getStack", name: "Error", stack: "Error: getS..."}

This example obviously creates an “in-place” stack trace and may not answer the WebSocket error from the original post but maybe others… And since this issue is the first result when looking for “IE11 Cannot parse given Error object” on Google, I thought this behaviour could be worth mentioning.
