I have followed up with the problems I had -- I needed a couple more logs to be able to troubleshoot better. BUT, Dylan, your solution (not repeating the part of the path to get to the Library, since identifying the library is sufficient) worked 100% . Thank you so much! Marked as Solved! You rock!

Hi Dylan! That stopped the errors. I have not managed to trigger what I wanted to trigger, but it's no longer breaking. I am going to fix it now, and I think I can, thanks to you! You are amazing. I don't know how to flag your answer as the correct answer.

I am going to try right away! Thank you, Dylan! ^.^
