Trying to wait for DOM mutations to stop but ends with Execution context was destroyed.
, any suggestion is welcome
page.evaluate(() => {
return new Promise((resolve,reject) => {
var timerId;
function resetTimer() {
clearInterval(timerId);
timerId = setTimeout(() => {
resolve(true);
}, 3000)
}
new MutationObserver(
() => {
resetTimer();
}
).observe(document.getElementById('root'), {
attributes: true, childList: true
});
resetTimer();
})
})
})
Protocol error (Runtime.callFunctionOn): Execution context was destroyed. undefined

The above snippet was run before getting a navigating lock on a page. Running the page.evaluate
between navigation can throw this error.
Found this from,
Fix was (at least in my case) to wait till URL changed and then page.evaluate
.
