Unable to use Polyspace PackNGo when the project name is the same as the filename

I have a Simulink project called "PolyspacePacknGoTest.prj" in MATLAB R2020b. I have a Simulink model inside a project called "PolyspacePacknGoTest.slx" and a test harness for my model called "PolyspaceHarness.slx". I am trying to use the "polyspacePackNGo" function for the test harness  and I am getting the following error:

>> zipfile = polyspacePackNGo('PolyspaceHarness')

### Starting Polyspace options generation for Embedded Coder

### Checking Polyspace Configuration:

Warning: For Polyspace code verification, MathWorks recommends that you either set 'InitFltsAndDblsToZero' to 'on' using the command line, or search for 'Use memset to initialize floats and doubles to 0.0' in the Configuration Parameters dialog box and clear the checkbox.

### Parameters used for code verification:

System : PolyspaceHarness

Additional Files : 0

Constraint input mode : DesignMinMax

Constraint parameter mode : None

Constraint output mode : None

Expected one output from a curly brace or dot indexing expression, but there were 2 results.

What is causing this?

[MathWorks Support Team]

The error is caused by the project and the Simulink model having the same name (Eg. "PolyspacePacknGoTest" shown below):

Project path:           W:\\PolyspacePacknGoTestModel\TestPolyspacePackNGo\PolyspacePacknGoTest

Simulink model path:

W:\\PolyspacePacknGoTestModel\TestPolyspacePackNGo\PolyspacePacknGoTest\slprj\ert\PolyspacePacknGoTest

 

To resolve the issue, change the name of either the file or the project to avoid shadowing.
