Bug encountered when upgrading to version 2.0.5 causing Desk tool crash with preview imagery.

Last updated: Oct 20, 2020
I just upgraded from 1.150.7 to 2.0.5, and I encountered a Desk tool crash whenever I try to go to a studio page that has any Preview imagery. Seems to occur on any page studio page that might show thumbnails or when I launch an image browser to view/select an image. Initially I thought it was because of using the
so I uninstalled that, but it’s pretty consistent crash error on any page with a preview. Is there something else I should do for an upgrade? I’ll include the stack trace on this thread.

And in case it might be the culprit, here is my schema for a document that shows this consistent crash. I’m not noting a preview or anything here so I’m relying on default system behavior for the thumbnails.

export default {
  name: 'screensaver',
  title: 'Screensaver',
  type: 'document',
  fields: [
      name: 'title',
      title: 'Title',
      type: 'string'
      name: 'asset',
      title: 'Content',
      description: 'Please select a series of images or videos',
      type: 'array',
      of: [
          type: 'image',
          title: 'Image',
          to: { type: 'image' }
          type: '',
          title: 'Video',
          to: { type: '' }

Hi David, thanks for reporting this one. I don’t think we’ve seen it before but it definitely looks like a bug. We’ll try to reproduce and get a fix in place 🙂

I think I know why this is happening and where the bug lives 👀 Will take a look tomorrow 🕵️‍♀️

Also it might be happening because your
in the schema are objects instead of arrays. Can you see if wrapping them in
fixes the problem?

Btw, why do you have
here by the way? I believe
is used when you have a reference type 🤔
          type: 'image',
          title: 'Image',
          to: { type: 'image' }

You are totally right
user H
. Removing the
block there resolved this. Seems we initially had these as reference types but switched over and never removed that line. We never got an error on 1.150 so thought it was okay. Thank you!
