everyitem().update() not work during script

hi

since few week i work with your collaboration on a script for open and update each link by recursion in my job file.

i have learn how to try to write a script with you, actually script is finish and correclty writed, but not work, because we have a doubt about this function everyitem().update()  can work during the script

i share with you a test file for indd22, with the script

I can also highlight a compatibility problem between illustrator and indisign concerning the updating of links between them. randomly (in the case of the lemon file, if you make changes in the ai file), you can either see the lemon in the final assembly, or a white square. and if you break the link and paste the watermark from illustrator directly into indesign, you no longer have this problem (at least for now)

2 programmers came to me, both telling me that the script should work, and that there is no reason, unless the api is not working correctly.

now I've been getting worked up about this script for several weeks, and two professionals have passed on it. I would like adobe support to take a closer look at my problem, because that's why there is a scripting forum?.... I know that telephone support is not competent at all.

we really think that updating links during the script is not done properly.

once the script is finished, I have an alert window that opens, in the background; the file looks ok, but when I click on OK, to really end the script, the outdated link symbol is put in place, and when I open the links, it is not up to date etc. ..

Thank you for your help, because I can't take it anymore. And I've spent too long to give up
