System Composer Interface Editor Generates "Failed to find element with UUID" when an interface is selected from its list.

When using the Interface editor embedded in the composition view, clicking on an interface or even just opening a library and using the buttons on the interface pane's control bar generates an error in the lower right hand of the interface editor that states "Failed to find element with UUID" followed by a UUID number. The exact same UUID numer is shown regardless of which interface in the interface editor is being selected. I seem to be able to assign the interfaces to ports and view them through the interface viewer, but I cannot use the "highlight port(s) using this interface".

Hi Brad,

Would you mind providing the reproduction steps for this issue?

Thanks!

Unfortunately, it's a rather large model and I'm not sure at what exact point the issue began. There is a master dictionary with several referenced dictionaries, and several reference architectures. The issue occurs anytime I click on an interface from the interface editor pane. When working properly, clicking on an interface in the interface pane will highlight interfaces in the composition view, but I instead receive the UUID error.

I'm in the process of testing each of the subarchitectures individually to isolate where the issue is.

Hi Brad, are you able to share the model with us so that we can take a closer look? Also, just to confirm, are you using R2023b?

@Kautuk Raj mentions - "The link seems to be broken...".

Indeed, the link is not working.

Correct - I am using MATLAB 2023b. Unfortunately, I can't share the model that is generating the error and I cannot seem to recreate the issue in a new, representative one that I would be able to share. It must be something to do with data dictionary type consistency. I tried deleting all interfaces from all blocks in the model and the error persisted.

@Brad Williams, do you have access to R2024a? If so, can you open the model in R2024a and see if the issue is resolved?

[Brad Williams]

I do have access, but it's not currently installed. I'll give it a try.
