Data Dictionary - Setup Worker Cache Issue

I tried the code from the matlab example -

spmd 
    Simulink.data.dictionary.setupWorkerCache
end

However, this generates an error -

Error using run4 (line 16)

Error detected on workers 1 2.

Caused by:

Error using Simulink.data.dictionary.setupWorkerCache (line 23)

Cannot set up worker dictionary cache. Dictionary cache is not in the default location.

Error using Simulink.data.dictionary.setupWorkerCache (line 23)

Any ideas on how to fix this issue? I am using 2016b.

Simply restart the parallel pool

Or first do

Simulink.data.dictionary.cleanupWorkerCache;

on each workers.
