Hi @Melih,
I tried to reproduce this error but I couldn't. I tried having a duplicate dictionary name and a duplicate file name that is not a dictionary. Are you able to readily reproduce this? Can you share the source material with us?

Hi Melih,
From what I understand, you are trying to create a dictionary by following the following syntax:
>>systemcomposer.createDictionary(“file_directory/dict_name.sldd”);
It is possible that there already exists a dictionary which was created with the same name. Try executing the following command:
>>Simulink.data.dictionary.closeAll
This will close all connections to open data dictionaries created previously. Alternatively, you could try closing a connection of a specific dictionary using:
>>Simulink.data.dictionary.closeAll(“file_directory/dict_name.sldd”)
After that retry creating the dictionary.
Hopefully, this resolves your error.
