after a second animation is invoked while a prior animation is still in progress using #angular/animations 4.0.2. if i let the first animation finish, the above error does not happen. how should i go about debugging this?
this was working in #angular 2.0.
EDIT: this seems to be this issue https://github.com/angular/angular/issues/16470

Tyring to unit test ag-grid-react with react testing library but unfortunately, I tend to be getting the same error over and over despite numerous attempts changing the how the component is rendered in the test.
When the tests are run, this error is thrown every time:
Error: Uncaught [TypeError: this.eIconWrapper.insertAdjacentElement is not a function]
The ag-grid-react version is at 25.1.0
I have also attempted this walkthrough: https://github.com/ag-grid/react-data-grid/blob/main/podcast-player/v8/src/PodcastGrid.test.js by waiting for the grid to be in the dom but still the errors persist:
console.error node_modules/react-dom/cjs/react-dom.development.js:19527
The above error occurred in the <AgGridReact> component:
in AgGridReact (at grid/index.jsx:229)
Further down the error seems to be pointing towards some sidebar component:
TypeError: this.eIconWrapper.insertAdjacentElement is not a function
at SideBarButtonComp.Object.<anonymous>.SideBarButtonComp.postConstruct
I'm using Dexie.js version 3.0.3-rc.3 in a Vue JS project and I occasionally run into this exception in Chrome (86):
Failed to execute 'bound' on 'IDBKeyRange': The parameter is not a valid key.↵ DataError: Failed to execute 'bound' on 'IDBKeyRange': The parameter is not a valid key.
Here's a screenshot of the full error:
I'm fairly certain the problem lies with something in my data being undefined, but I'm trying to find a good way to troubleshoot this. I paused the Chrome dev tools on exceptions and inspected the code around this particular part of Dexie, but it doesn't reveal what data was used to make this exception occur.
Does anyone have any suggestions on how to find out what's actually wrong? It feels a bit like a needle in a haystack.

Below is the full call stack:
Try inspecting the call stack. I know it can be long until you reach a frame within your application code, but the failing call should be there!
this might be silly, Is there any way to automatically place a debug point when an error pops up in MATLAB
Error popping is done manually by
msg = 'Error has occurred'
error(msg)
What I need is, to automatically put a debug (not by manual intervention) after popping this error.
You can use dbstop with a condition:
dbstop if error
MATLAB pauses at any line in any file when the specified condition
occurs.

Finally, I got it fixed!!! I'm using cloud_firestore in my app, the userId I was trying to access in my widget tree was not yet available at the time of render. I figured this out by wrapping the root widget return statement in a trycatch block, as soon as I did this, The error stopped since its being handled and I printed the error to the console, then I returned a progress loader in the catch block.
The error popup with the following error message comes on the screen repeatedly when application is in idle state (no user activity is performed).
Error occurred on client: (TypeError): Unable to get property 'iterator_0' of undefined or null reference.

Can anyone give some pointers to navigate to the problamatic area in the code?
The fact that you're getting it repeatedly is probably due to the fact that you're performing an action on a timer (i.e. perform repeatedly an action).
From the small snippet you've shown, I don't think there's anything we can deduce. Do you have a larger stacktrace? It is still possible the error is in your own code (trying to invoke iterator() on a null object).
