Uncaught TypeError: _jp.xxxxxx is not a function

Hi everyone - happy new year,

Since upgrading from Meteor 2.12 to 2.13 I have been setting numerous errors with a similar format to this in MontiAPM which seem to have to do with socksjs? The names of the functions seem random but all start with _jp:

Anyone have any ideas what is could be about? Should I be concerned?

I noticed there was some mention of a setting in 2.14 to possibly do with socksjs? Is that related:

You can now set DISABLE_SOCKJS_CORS=1 if you want to prevent SockJS from setting CORS headers. Do not set this option if you will have DDP clients from other origins connecting to the DDP server. PR
