Getting error TypeError: Cannot set properties of undefined (setting 'endEventIdx')

[engcom-Hotel]

When we are running profiler on any page after some time we get this error;

TypeError: Cannot set properties of undefined (setting 'endEventIdx')

Please fix it ASAP.

Thanks

Please fix it ASAP.

I think there is something you don't understand about OSS

[engcom-Hotel]

Yes, please help in understanding the same. :-)

frame is undefined in this case.
You can see the code there: https://github.com/search?q=repo%3ANoiseByNorthwest%2Fphp-spx%20endEventIdx&type=code

That means in this case the array has no elements or an element with undefined as value (see https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/pop), which can be easily checked.

Pullrequests are welcome @engcom-Hotel.

I don't see what could cause this.stack.pop() to return undefined here except a corrupted report.

@engcom-Hotel can you share a screenshot of all errors that appear in the browser console, when this happens?
