Photoshop batch-apply 'Last Filter' works for every filter EXCEPT Liquify

[tutmoses]

This script takes the last filter that was applied and repeats it on all selected layers and masks. (It is designed to avoid the need to collapse layers into a smart object in order to batch-apply filters).

However, there's a bug in it that I can't figure out: it works beautifully for something like Gaussian Blur, but for Liquify, it records in the history that the filter has been applied, yet the layers remain untouched.

Steps to reproduce: 1. Blur layer 1. 2. Select layers 2 (masked) & 3 (unmasked) 3. Run script 4. Repeat 1-3 but with liquify instead of blur.

runMenuItem(cTID("LstF"), true);

Seems to work fine. It would fails if a filter has not been used yet in the current Photoshop Session.  And the last filter can fail if an inappropriate layer is current.

However  in the script you posted it look like it will not be executed its comment out in main

Thanks for your reply. It looks like it was commented out but that was just a quirk of the copy/paste into this dialogue box unfortunately.  I've edited the question now.

Were you able to make it work?

In other words the  Script may work the script may or may not work.   It depends on condition.  The only thing the script catches  is a layer not having a layer mask.   The use of the two functions were comment out so I did not the two functions.  I just checked to see if  run menu item last filter works. And saw it would not be available if a filter has not need use in the Photoshop session and that if the filter was inappropriate for the layer the filter would fail. The script is not coded to tolerate failure in the functions.

Some kind of bug.
What version of photoshop do you have?
I have it on 21.2.2. runMenuItem for liquify does not work at all (the liquify window is just called). Possibly due to a disabled GPU.
When the GPU is on (and photoshop does not detect GPU for me), photoshop crashes on liquify.
Try to execute instead of runMenuItem (by the way, why are you sending "true" as the second argument?)

executeAction(charIDToTypeID("LqFy"), undefined, DialogModes.NO);

Works great on CS6.
