Hi, we have a problem with custom components that used to work before. The components have sub fields that user can add list of item e.g. FAQ question and answer.

It stops working today with the warning in console when we try to add those components into the page.

Hi @maythee,

This could be a potential bug, we are investigating this further to figure out the root cause. However, as a workaround enabling **Use debounced edits in content editor** option under Account Settings → Advanced Settings → Performance seems to resolve the issue on your space.

Also, could you tell us about your tech stack and `@builder/react` SDK version, so that we can reproduce this from our end? Thank you.

Hi @maythee,

We are glad to hear that. We still would like to investigate this further, so if could you tell us about your tech stack and `@builder/react` SDK version, that would be much appreciated. Thank you!

Hi @maythee,

Looks like you are using an older version of React SDK, if you have the option to upgrade to our latest React SDK

```auto
    "@builder.io/react": "^3.0.2",

```
