It would really help if you provided a screenshot of your relevant blocks, so we can see what you are trying to do, and where the problem may be. Also which extension are you using? Any link?
To get an image of your blocks, right click in the Blocks Editor and select "Download Blocks as Image". You might want to use an image editor to crop etc. if required. Then post it here in the community.

Sorry, I haven't put any blocks. I tried dragging the extension to the components panel and then it shows the that error. My blocks are empty:sob:. After I tried other extensions like i used previous project.. it shows there too. so i think falt is not on the extention or cording:cry:. can you help me this extention error on this topic or do i creat another topic? .Because it is a problem related to something else.
Several users appear to be getting this error
Try again, to see if it continues to happen everytime. Many have found it goes away.
