Error: Simulink supports signal and parameter dimension size up to 2147483647, which is the maximum allowable 32-bit signed integer

While complining my model I get the following error message.
"Simulink supports signal and parameter dimension size up to 2147483647, which is the maximum allowable 32-bit signed integer value. Consider reducing the signal or parameter size before compiling or simulating the model."
I have marked the position where the error appears in yellow in the screenshot.
I am especially surprised that the problem in the upper "Composite Entity Creator 2" this problem does not appear, so I assume that the problem is due to the functions stored in the entity server "Withdrawl". Here, on the one hand, "getAttribute(a1)" is executed at the input and "genNextResource()" at the output:
The inside of the "Resource Acquirer" is build as following:
The entity that enters the system has 18 attributes. Their values are mostly 0 or integers, a decimal value is also stored via a timestamp.
If I attach the input port 1 (i.e. the input "Warehouse") to a scope and comment out the rest, however, the entities arrive regularly with the values that are to be expected.
What can it be related to?

The error message you are encountering seems to be a bug in the 2020b release of MATLAB. I had also encountered the same error while using R2020b and was able to get rid of the error by upgrading to release R2022a. Hence, I would suggest updating to a newer version of MATLAB.
