I've been working very well before, but I suddenly got the following error when saving these two days.

When I try to comment out the date field, the error disappears, and when I reuse it, it goes wrong again. It can be determined that the problem is the date field, and it is the same error to change the date field to a datetime field. Please help me analyze the reasons.

TypeError: format() expects a string or boolean:false parameter function()
{var args=(arguments.length===1&&$.isArray(arguments[0]))?arguments[0]:arguments;var formattedString=this;for(var i=0;i<args.length;i++)
{var pattern=new RegExp("\\{"+i+"\\}","gm");formattedString=formattedString.replace(pattern,args[i]);}
return formattedString;}
