Can’t add frequency domain field profile into structure group using script

Hi Devika,
I've added a copy of the script along with an image of the parameters I've set in the structure group below. I've also attached an image of the produced structure.The script is just a modified version of the included script to produce a photonic crystal with a square lattice. I've added extra functionality to add input and output waveguides and change the structure of the crystal. Now I want to add a frequency domain field profile to the output waveguide. I've used the example script for the "addprofile" command but it seems to be not valid in my case.
I'm new to scripting in Lumerical Mode so please let me know if I've missed anything thank you.

Thanks for shairing more details:
Are you adding
”addprofile” in
Structure group? That could be the reason of error.
You won’t be able to add the profile monitor there. Its only for the structure . You can add monitors in analysis group. Or you can use any of the following options.
Option 1:
You can create an lsf file from Script file Editor on the right side of window and add profile monitor
Option 2:
add the monitor inside the model script.
I will recommend this course material: Ansys Lumerical Scripting – Learning Track | Ansys Innovation Courses
Please let me know this solve the problem.
Thanks and regards
Devika
