trackJS XML Parsing Error: no element found in firefox

Question

I have implemented trackJS library for better debugging and logging. But whenever I send any error to trackJS it throws error only in Firefox. XML Parsing Error: no element found Location: https://capture.trackjs.com/capture?token=<tokenid> Line Number 1, Column 1:

here's the code I am using to push errors to trackJS.

trackJs.console.error('some error msg.');

please let me know if I am doing anything wrong here.

This is a old Firefox bug, there is no need to return a payload from the TrackJS error capture API, so we do not. The warning shown in the Firefox console is local-only. It can safely be ignored.
