Error in Gravity Forms block rendering when using Ultimate Member

I’m getting an error “Error loading block: Invalid parameter(s): attributes” on Gravity Forms block in the editor and the form preview can’t be rendered when using Ultimate Member. It seems to be an error in the block-renderer Rest API call and points to a problem with parameter “um_is_restrict” that I assume Ultimate Member sends to control the block visibility.

If Ultimate Member is disabled, the form block works without errors and shows the preview in editor. The form block has also worked earlier with the same setup on this site so it has likely been introduced with either GF or UM update quite recently(ish).

Not sure if this is something that should be fixed in Gravity Forms or Ultimate Member though so I’m reporting this to both plugins’ developers.
