 * Hi,
 * For each block I create with Lazy Blocks, I get the message “Error loading block
   preview: [object object]”.
    I’ve also tested to copy 1:1 your shortcode example.
   Same issue.
 * Screenshots:

 * Hi [@nko](https://wordpress.org/support/users/nko/),
 * I found the issue: there is a plugin conflict with iThemes Security.
    The setting“
   Filter long URLs” trigger this.
