Cannot set property stack of [Error (E_UNKNOWN) Encountered an unexpected error] which has only a getter

[tjwebb]

I get this on an unhandled error on bluebird. Node 0.10.32 (tried also on 0.11, 0.12, and io 1.6), bluebird 2.9 (also tried on 2.6). Any ideas?

node_modules/bluebird/js/main/captured_trace.js:54
        error.stack = stack.join("\n");

TypeError: Cannot set property stack of [Error (E_UNKNOWN) Encountered an unexpected error]  which has only a getter

Waterline's WLError doesn't allow setting .stack, it only defines a getter not a setter

I think you know more about how this works than I do. How is it that a property becomes un-settable?

[petkaantonov]

Waterline does something like this:

"use strict";
function WLError() {}

WLError.prototype.__defineGetter__("stack", function() {
    return "...";
});

var e = new WLError();
e.stack = "..."; // Throws an error because there is no setter
