Describe the issue

I recently encountered an issue while selecting a date in the system. The data-value being generated for the selected date was incorrect. For example, when I selected January 12, 2025, the system returned 12-00-2025 instead of the correct value.

After investigating, I discovered that the issue was due to the month value not being properly adjusted. It seems the month index was not incremented by 1, which is required since months in many programming languages (like JavaScript) are zero-based.

I was able to resolve this on my end by adding a month conversion adjustment (+1) in the code. However, I wanted to bring this to your attention in case other users might be affected.

Original code:

      _dateToDataValue(date) {
          if (!DateTime.isValid(date))
              return '';
          return `${date.year}-**${date.month.toString().padStart(2, '0')}**-${date.date
            .toString()
            .padStart(2, '0')}`;
      
```}

Here is the corrected code:

 _dateToDataValue(date) {
      if (!DateTime.isValid(date)) return '';
	  **let setMonth = parseInt(date.getMonth() + 1).toString().padStart(2, '0');**
	  return `${date.year}-**${setMonth}**-${date.date.toString().padStart(2, '0')}`;
  };
