Error Attempting to Back Annotate Stratix X using Quartus 21.2

I am attempting to use the back annotate functionality outlined in the Intel Scripting Guide on a Stratix 10 device using Quartus Prime Pro 21.2 with the example code shown below: https://www.intel.com/content/www/us/en/programmable/documentation/sbv1513989262284.html#dgc1605834946145.

## Print out all the back-annotation assignments
set asgn_col [get_back_annotation_assignments]
foreach_in_collection asgn $asgn_col {

    ## Each element in the collection has the following
    ## format:
    ## { {<Source>} {<Destination>} {<Assignment name>} {<Assignment value>} {<Entity name>} }
    set from   [lindex $asgn 0]
    set to     [lindex $asgn 1]
    set name   [lindex $asgn 2]
    set value  [lindex $asgn 3]
    set entity [lindex $asgn 4]
    puts "$entity : $name ($from -> $to) = $value"
}

I've attempted to execute the get_back_annotation_assignments command via the tcl GUI (as shown in the attached image) as well as launching the script above passing it in as a script for quartus_cdb. Both options produce the same error.

Does anyone have any suggestions as to what's causing the issue? As you can clearly see, the design is compiled in the image.
