App is Suddenly Blank

App Building
1

Hello,

My app suddenly became blank while I was editing it, and I cannot find a way to make it work. I don't remember exactly what I was doing when it went blank, unfortunately.

I've tried (with no success):

  • Reverting to a previous version
  • Reverting to a previous version using the _historyOffset param
  • Exporting to JSON and importing it in a new app
  • Looking at the debug console for clues about an issue

This issue seems to have happened to other people, but the solutions are personalized and undisclosed (at least the ones I have found).

Initially the app appeared blank and the component tree loaded normally:

After messing with the history, the components dont load anymore:

I tried uploading the exported json, but I am unable to upload an attachment given I am a new user.

Would appreciate any help, this dashboard is pretty important to our company's day to day.

Thanks,
Reynaldo

It seems I can now upload attachments:
Applications.json (554.9 KB)

Hey @rfariaszorrilla

If you have this kind of problem then run the query from the history.

Hi @WidleStudioLLP !

What do you mean by run the query from history? Which query?

Hi @rfariaszorrilla, welcome to the forum!

I'm sorry you're experiencing this issue. I imported your app's JSON and see the same thing as you.

Could you share a screenshot of your history tab? There should be one or more Ran migrations entries. Please revert to the version before the one closest to the date when you stopped seeing components on the canvas.

Hi Paulo!

Thanks for the reply, here is the screenshot:

I've reverted to the one in Jan 4, now my history looks as follows:

The canvas still shows no components. Not sure if this was what you expected, so I've exported the app again with the revert in case that is what was needed:
Applications (1).json (1.0 MB)

Let me know if there is anything else you need!

Thanks for the screenshots and the new export! I've surfaced this internally and will get back to you with our findings.

Hi @Paulo!

By any chance do you have any findings?

Hi @rfariaszorrilla, check your DMs. :slightly_smiling_face:

We don't know exactly what caused a Container component to become a parent component of itself. We solved this issue internally by removing the compromised component and sending the new app export to @rfariaszorrilla.

If you experience a similar issue, please DM me the export of your app as an attachment so we can investigate it further.
