[General Inquiry]: XMLHttpRequest error

[p-obrien]

What is your general inquiry?

On a busy website I'm receiving thousands of errors reporting events like the below:

Unfortunately the line numbers reported just point at a XMLHttpRequest exception so I'm having trouble understanding what is the cause of this error is or how to avoid it:

Hi, v1.0.2 is an extremely old version of the web client and has known issues. Is there a reason you are unable to upgrade?

As for the error, it looks like there is an error in initializing new t, but it's unclear what this object's purpose is because the name has been minified. Have you confirmed that your network conditions are healthy?

I would recommend upgrading before further investigation.

v1.0.x should be considered deprecated
