How do I generate code for a Radar Toolbox "radarTracker" object when a uint32‑to‑double type mismatch occurs in Simulink R2025b?

I am using Simulink R2025b with Radar Toolbox to generate code for a model that includes a supported “radarTracker” object . When I update the model (which triggers code generation), the update fails with a data type mismatch error.

During model update, I receive the following error:

Error: Unable to write a value of type uint32 into a variable of type double.
Code generation does not support changing types through assignment.
To investigate the cause of the type mismatch, check preceding assignments
or input type specifications.

Function 'GNNTracker.m' (#41.55492.55500), line 1188, column 25:
"trackPDs"

How can I resolve this code generation error?

objectDetection or radarTracker require the double precision inputs. To resolve this issue in MATLAB R2025b, please ensure that all calls use datatype "double". For example:

detection = objectDetection(t, [x; y; z], ...
    'ObjectAttributes', struct('TargetIndex', double(id)));
