Hello NN,
I think your issue can be better resolved with more information, perhaps the model and what parameter you are using as the key. From the error message, it looks like you are trying to access a key (parameter) that does not exist in your container, such as a structure, map, or cell array.
To resolve this issue, first try verifying if the key you are trying to access is valid and exists in the container. You can use the "isfield" or "iskey" functions to check if a particular field or key exists in a structure or map, respectively, before trying to access it.
If you are sure that the key you have specified exists, then attach your model which will help in resolving your issue further.
Hope this helps !
