Non-blocking Error shown in console when uploading images to galleries

[chriskmnds]

Describe the bug

An Unhandled Promise Rejection Error is shown in the console when uploading images to the Offset, Masonry, and Stacked galleries. This happens on CoBlocks version 1.20.1.

This is a non-blocking error, since the images are uploaded as expected. The Error is shown only on the first upload - it seems to be cleared on consecutive ones.

Tested in Chrome & Safari.

To Reproduce
Steps to reproduce the behavior:

1. Insert a new Gallery (Offset, Masonry, or Stacked).
2. Click on "Upload" at the bottom - should upload image as expected.
3. See error in console.

I am not seeing this issue running CoBlocks 1.2.0 in Chrome. Can someone else test and confirm this is a bug in CoBlocks?

I'm also unable to replicate this - @chriskmnds are you still seeing the issue?

This issue is no longer present in CoBlocks 2.9.1.
