Is there any way to bypass minRowCount validation when the question is not mandatory in matrixdynamic?

Hi,

Is there any way to bypass minRowCount validation when the question is not mandatory in matrixdynamic?

{
 "pages": [
  {
   "name": "page1",
   "elements": [
    {
     "type": "matrixdynamic",
     "name": "question1",
     "columns": [
      {
       "name": "Column 1"
      },
      {
       "name": "Column 2"
      },
      {
       "name": "Column 3"
      }
     ],
     "choices": [
      1,
      2,
      3,
      4,
      5
     ],
     "isRequired": false,
     "rowCount": 1,
     "minRowCount": 1,
     "maxRowCount": 5
    }
   ]
  }
 ]
}

For above json, My client wants to hide the Remove button when the rowCount: 1. I found minRowCount: 1 can do the trick, but it still prompt an error message when I validate the form.

Thanks.

@KLC215 Sorry, for misunderstanding. Finally I can see the issue. Got it. You can use survey.onSettingQuestionErrors event to modify question errors. Here is the code

survey.onSettingQuestionErrors.add(function(sender, options) {
    for (var i = options.errors.length - 1; i >= 0; i--) {
        if (options.errors[i].getErrorType() === 'minrowcounterror') {
            options.errors.splice(i, 1);
        }
    }
});

And here is the example.

Thank you, Andrew
