mod_to_canvas.p(0): RenderPins failed: failed,-50

Hello. I'm trying to create a custom module using the guide here https://documentation.dspconcepts.com/awe-designer/latest-version/matlab...(8.D.2.5)MATLABFunctionReference-new_pin_type.mnew_pin_type.m . However, I run to this error when I try to deploy the module in audio weaver:  mod_to_canvas.p(0): RenderPins failed: failed,-50,in_right in_left in_right_scratch in_left_scratch coordinate1 coordinate2 coordinate3,out_right_scratch out_left_scratch out_right out_left. For reference, these are the pins that I declare in the Matlab code:

PT=new_pin_type([], [], []);
PT_1=new_pin_type([], [1], []);
PT_32=new_pin_type([], [32], []);
add_pin(M, 'input', 'in_right', 'Input signal right', PT);
add_pin(M, 'input', 'in_left', 'Input signal left', PT);
add_pin(M, 'input', 'in_right_scratch', 'Input signal right', PT_32);
add_pin(M, 'input', 'in_left_scratch', 'Input signal left', PT_32);
add_pin(M, 'input', 'coordinate1', '', PT_1);
add_pin(M, 'input', 'coordinate2', '', PT_1);
add_pin(M, 'input', 'coordinate3', '', PT_1);
add_pin(M, 'output', 'out_right_scratch', 'Output signal scratch right', PT_32);
add_pin(M, 'output', 'out_left_scratch', 'Output signal scratch left', PT_32);
add_pin(M, 'output', 'out_right', 'Output signal right', PT_1);
add_pin(M, 'output', 'out_left', 'Output signal left', PT_1);
