Line 57 of the above module reads as follows:
_raiseQueueError (name) {
const self = this
return function raiseQueueErrorInternal (errObj) {
const message = `Event: ${name} error`
logger(message, self.id, errObj)
self.emit(enums.status.error, self.id, errObj)
return Promise.reject(errObj)
}
}It is a helper function that gets used throughout the queue.js file.
I was writing the following test code to test the _raiseQueueError and _raiseQueueErrorInternal functions:
const testErr = new Error('test')
const raiseErr = qReady._raiseQueueError('error function name')
return raiseErr(testErr).catch((err) => {
t.equal(err.message, 'test', 'raiseQueueErrorInternal returns error object')
})This causes the following error in the SSH console:

So reading on the Domain - Additions to Error Objects page it is obvious that the domainEmitter property is trying to be added to the string value above.
When I wrote the API for the job queue module I decided to go with a standard of always returning the Queue.id as the first argument for all events.
If I change it now it will require a major version bump due to the API change. If that is the case so be it however it seems like node.js should be looking at the type of object the first argument is and preventing this exception.
If I am just doing everything wrong then I'll change it.
Thanks.
