Hey there,
Thanks for the report! We did remove absoluteRect() on Sketch 97. Here’s a quick workaround a user shared on our forums that might help in this case.
However, you seem to be having this problem with Sketch 71.3. Would you mind sharing more details about your setup? Like macOS version, and confirm that you are using Sketch 71.3 (Which should still have absoluteRect() in it)
