How can we store both a single JSON error and an array of errors in the same variable using Javascript?

My server sends me JSON with a list of errors. If there is more than one error, it looks like this:

{
    "ErrorFuncional": [
        {
            "ErrorCode": "1020",
            "ErrorReason": "xxxx",
            "ErrorPosition": "xxxx",
            "OriginalValue": "33333"
        },
        {
            "ErrorCode": "103",
            "ErrorReason": "xxxx",
            "ErrorPosition": "xxxx",
            "OriginalValue": "111"
        },
        {
            "ErrorCode": "110901",
            "ErrorReason": "xxxx",
            "ErrorPosition": "xxxx",
            "OriginalValue": "222"
        }
    ]
}

But if there is only one error, the JSON looks like this:

{
    "ErrorFuncional":
        {
            "ErrorCode": "1020",
            "ErrorReason": "xxxx",
            "ErrorPosition": "xxxx",
            "OriginalValue": "33333"
        }
}

I defined the errors variable as an array, so when trying to parse one error, an exception occurs.

Is there a way to convert a single error into an array with one element before parsing it to JSON? If not, how should I handle this scenario?

Thank you!

Give this a shot.

let NewErrorFunc = {
  "ErrorCode": "2020",
  "ErrorReason": "yyyy",
  "ErrorPosition": "yyyy",
  "OriginalValue": "55555"
};
    
function changeIntoArray(array)  {
  if (Array.isArray(array) === false) {
  return {NewErrorFunc: [array]};
} else {
    return {NewErrorFunc: array};
  }
}
    
console.log(changeIntoArray(NewErrorFunc))
