Dear PyGUI <built-in function add_static_texture> returned a result with an exception set

Question

enter image description here

Problem:

I'm coding a movie search program. I'm having trouble displaying the poster when clicking on any genre.

Python Exception message:

Error loading texture for poster/155.jpg: <built-in function 
add_static_texture> returned a result with an exception set

Attempted Solutions

I tried removing:

posterImg = dpg.add_static_texture(width2, height2, data2, 
                                   parent="Genresults_list")
dpg.add_image(poster_path, width2, 
              height2,parent="Genresults_list")

and I realized there seems to be an issue with loading the image. Before posting here, I tried loading the image in a different context and it worked fine (meaning the image file exists and is not corrupted).

This is my first time using Dear PyGUI, so there's a lot I'm still unsure about. Any help would be greatly appreciated.

Code:

    genre = user_data

    if not dpg.does_item_exist("Genresults_list"):
        print("Error: 'Genresults_list' does not exist!")
        return

    dpg.delete_item("Genresults_list", children_only=True)  # Clear old results

    if movies:
        row_counter = 0  
        current_row = None  
        for movie in movies:

    else:
