I have a front end written in Elm, and it is communicating with a Phoenix back end through channels. However, it seems phoenix.js is doing something to the DOM. If the page is idle for a while, I get DOM-related errors in the console, for example:
Uncaught TypeError: Cannot read property 'childNodes' of undefined
or
elm_db.js:3699 Uncaught TypeError: Failed to execute 'removeChild' on 'Node': parameter 1 is not of type 'Node'.
How can I prevent phoenix.js from messing with the DOM?
Edit: Here are two screenshots from the console:
client_ledger.js and client_db.js are my client files that receive and send json objects over the Phoenix channels. elm_ledger.js and elm_db.js are my compiled Elm front ends.
