slashrsm commentedLooks good to me. Could you provide more background info (which display plugin, how embed code for existing embed looks, steps to reproduce)?

recrit commented@slashrsm - it was the lightning media browser.
I uploaded the missing screenshot: https://www.drupal.org/files/issues/screenshot_257.png
It would get stuck / stopped at that step, and then the error message would be logged.

slashrsm commentedScreenshot doesn't say much. Could you share steps to reproduce this in Lightning? I doubt that this error can stop embedding from working all together. It is just a notice after all. What happens if you press "Next"?
Does the patch fix the problem with embed stuck on that page?
Comment #8
recrit commentedPatch fixes the issue. Same issue as seen on #2786493: EntityEmbedDialog causes undefined index notice if no embed display settings are presented to the user only for existing content.
