Access a different input-argument, when calling a fucntion

For my Real-Time model in Simulink, I use "MATLAB Function" in which I need to specify, that one specific array (in my case, it is "H_R") is going to have variable-size dimensions from [1 1] to [1 125]. For that, I was trying to use the function coder.varsize(). However, when compilating, I receive an error:
Output 'H_R' has variable size but the upper bound is not specified; explicit upper bound must be provided.
In order to fix this error, It is needed to access the argument "ubounds" in the function coder.varsize(), but unfortunetly it is not possible and Simulink thinks I am trying to specify another variable:
Is it a bug or am I missing something? How can I access the "ubounds"-argument?
P.S. In the documentation example, the upper bound is also represented without a comma (i.e. [1 5]), but I think it is just a typo.
P.S.S The "variable size" is also allowed in the "Model Explorer"

This error message suggests you to open the Symbols pane in the MATLAB Function block and enter the upper bound size for this output (H_R) in there (check the "Variable size" checkbox and enter the size as [1, 125] in the dialog). Same can be done in the Model Explorer. Can you please try that and see if the error goes away?
Once you do that, you can remove the coder.varsize declaration.
