HELP! Error Message "Cannot read properties of undefined (reading 'type')"

[OLIVIALUNSFORD]

Help! I have been working on this for the last week and I went to complete my home page for the experience today and this happened. I now can't see my pages in the Contents pane, and I can't edit this one with the Contents Pane editor options. I'm freaking out... what do I do? I have a presentation next Wednesday and was hoping to showcase this.

Is it possible to share your app in some way for us to take a look?

Here is the experience. I was working on the "Need To Know" Page when this happened. I was going to implement hover cards with descriptions for project phases that the user will see on the second page. 

But I literally can't even access the Pages section of ExB to delete or add Pages anymore. I was going to delete this one and just start over because of the error, but there's no way to back track.

I cannot access it unfortunately

[OLIVIALUNSFORD]

Sorry - give it a try now.

I can see it now and we will take a look at it. In the meantime, it would be helpful if no further savings are done. Thanks for bringing it up.

Hello @OLIVIALUNSFORD -

After checking, the widget causing the problem has been identified, but we are not sure what configurations had been done prior to this - it is quite weird and probably needs certain specific pre-steps.

The good news is - there is a way for you to resolve this issue on your end.

1. In the builder canvas, select 'Card 2', and then delete it:

2. Save the app and then refresh the browser. It should look fine now.

All you have to do now is to add another Card widget as a replacement and continue building the app.

Thank you,

Tonghui

That worked! THANK YOU!

I am having this issue with the search widget - after it was previously working. When I try to add an action is pops  up with that error.

@Laura Which environment and version are you using? If it's AGOL, can you share the app with us to take a look at? Thanks.
