R2022a, Failed to evaluate mask initialization Caused by: Too many input arguments

This code worked in R2019b and R2020b, but does not in R2022a:

set_param('pathofblock/name_of_blockwithmask','RAM_type',RAM_type); % RAM_type is either 'BRAM' or 'URAM'

Error in 'pathofblock/name_of_blockwithmask': Failed to evaluate

mask initialization commands.

Caused by:

Too many input arguments.

after looking into it further I found that R2022a has wrapped the intialization code in another function that doesn't include the arguments I had in my function...

R2019b version of mask code:

init_foo(gcb,...

RAM_type,RAM_type_prev)

R2022a version (converted by matlab when i opened model in R2022a):

% Initialization code section

function initialization()

init_foo(gcb,...

RAM_type,RAM_type_prev)

end

% Parameter callback section

I found the problem!

I was calling...

add_block('Simulink/Commonly Used Blocks/Subsystem',[sys '/' subsystem_name ]); %add subsystem

and with R2022a this capital 'S' is no longer recognized, you must use the small 's'.

(in R2020b and before this capital 'S' worked fine, I guess the folks at mathworks no longer like Tower of Power :) )
