I want connect line from in1 to terminator

1. I disconnect the existing line.
2. Create Terminator
3. Connect from input to terminator

But, Occur error add_line (Error: Invalid simulink Object name).

How to solve this Error.

mdl = "test_model";

% system load
load_system(mdl);

% IO list loads
inports = find_system(mdl, 'SearchDepth', 1, 'BlockType', 'Inport');
outports = find_system(mdl, 'SearchDepth', 1, 'BlockType', 'Outport');

%   find_system Prop (model name, find type, find type select, value, value type)
inports_suffix = inports_cell(mdl, inports);
outports_suffix = inports_cell(mdl, outports);


[inport_num,] = show_prompt(inports_suffix);
terminate_inport(mdl, inport_num, inports_suffix, inports);

%   IO ports name subsystem/portsname -> portsname change func.
function inports_name_cell = inports_cell(mdl, inports)
    inports_name_cell = cell(1, numel(inports));
    for i = 1:length(inports)
        inports_name_cell{i} = erase(inports{i}, [mdl, '/']);
    end
end


function [show_prompt_idx,show_prompt_tf] = show_prompt(inports_suffix) % inport block name prompt
    inports_name = strrep(inports_suffix,'/1','');
    [show_prompt_idx,show_prompt_tf] = listdlg("SelectionMode", "single", "ListString", inports_name); % 입력값을 텍스트로 반환
    
end


function terminate_inport(mdl, inport_num, inports_suffix, inports)
    term_block_name = ['Terminator_', num2str(inport_num)]; % Terminator 넘버링
    term_block_path = mdl + '/' + term_block_name; % Terminator 경로와 이름 합치기
    if(getSimulinkBlockHandle(term_block_path) == -1) % Terminator 가 없다면
        position = get_param([inports{inport_num}], 'Position'); % inport블록의 위치 반환
        
        left = position(1); % 1은 x좌표 
        top = position(2); % 2는 y좌표
        right = position(3);
        bottom = position(4);

        add_block('simulink/Sinks/Terminator', term_block_path, 'Position', [left-80, top,left-70, top+14]); % terminator블록 생성
        lines = get_param(inports{inport_num}, 'LineHandles'); % inport에 연결된 line정보 반환
        terminators_suffix = [strrep(term_block_path,[mdl,'/'],''),'/1']; % Terminator의 경로를 제거하고 이름만 남긴 뒤, 포트 번호 입력
        delete_line(lines.Outport);
        add_line(mdl, inports_suffix{inport_num}, terminators_suffix); % inport 와 Terminator 연결
    else % Terminator 가 있다면
        disp("Terminator already exist.");
    end
end

In order to find the precise cause and solution for the issue you are currently experiencing, I believe that the following additional information would be necessary. If you could provide the following information, it would enable contributors, including myself, to assist you more effectively:

1) Detailed description of the issue

2) Example files and data files that can reproduce the issue

• What's the "model"?
• What's the "inports_cell"?
• etc

3) Exact steps to reproduce the same problem using the files you provided

4) All error messages that appear when the issue occurs

I have temporarily fixed your script. You can use outport and inport handles as mentioned in add_line. Please fix the script as you need.

mdl = "test_model";

% system load
load_system(mdl);

% IO list loads
inports = find_system(mdl, 'SearchDepth', 1, 'BlockType', 'Inport');
outports = find_system(mdl, 'SearchDepth', 1, 'BlockType', 'Outport');

%   find_system Prop (model name, find type, find type select, value, value type)
inports_suffix = inports_cell(mdl, inports);
outports_suffix = inports_cell(mdl, outports);


[inport_num,] = show_prompt(inports_suffix);
terminate_inport(mdl, inport_num, inports);

%   IO ports name subsystem/portsname -> portsname change func.
function inports_name_cell = inports_cell(mdl, inports)
    inports_name_cell = cell(1, numel(inports));
    for i = 1:length(inports)
        inports_name_cell{i} = erase(inports{i}, [mdl, '/']);
    end
end


function [show_prompt_idx,show_prompt_tf] = show_prompt(inports_suffix) % inport block name prompt
    inports_name = strrep(inports_suffix,'/1','');
    [show_prompt_idx,show_prompt_tf] = listdlg("SelectionMode", "single", "ListString", inports_name); % 입력값을 텍스트로 반환
    
end


function terminate_inport(mdl, inport_num, inports)
    term_block_name = ['Terminator_', num2str(inport_num)]; % Terminator 넘버링
    term_block_path = mdl + '/' + term_block_name; % Terminator 경로와 이름 합치기
    if(getSimulinkBlockHandle(term_block_path) == -1) % Terminator 가 없다면
        position = get_param([inports{inport_num}], 'Position'); % inport블록의 위치 반환
        
        left = position(1); % 1은 x좌표    
        top = position(2); % 2는 y좌표
        right = position(3);
        bottom = position(4);

        add_block('simulink/Sinks/Terminator', term_block_path, 'Position', [left-80, top,left-70, top+14]); % terminator블록 생성
        lines = get_param(inports{inport_num}, 'LineHandles'); % inport에 연결된 line정보 반환
        delete_line(lines.Outport);
        
        %%%%%%%%%%%%%%%%%%%%%%%%%%%% TEMPORARILY FIXED %%%%%%%%%%%%%%%%%%%%%%%%%%%%
        paramOut = get_param([inports{inport_num}], 'PortHandles');
        paramIn = get_param(term_block_path, 'PortHandles');

        add_line(mdl, paramOut.Outport, paramIn.Inport); % inport 와 Terminator 연결
        %%%%%%%%%%%%%%%%%%%%%%%% TEMPORARILY FIXED DONE %%%%%%%%%%%%%%%%%%%%%%%%%%%
    else % Terminator 가 있다면
        disp("Terminator already exist.");
    end
end
