Get last created daily not / template doesn't work

[al01387]

I'll try to find a script to display the last created daily note, even if the last one wasn't written yesterday, but a few days ago.
This is my script:

<%*
var lastDateCheck;

// Recursively find last daily note that was created
// Because sometimes I skip a daily note

function lastNoteChecker (lastNumber) {
    lastDateCheck = tp.date.now("YYYY-MM-DD dddd", -lastNumber);
    if (tp.file.exists(lastDateCheck))
	    return lastDateCheck;

  // Only check last 50 days
  if (lastNumber > 50) {
     return 0;
  }
    else {
	    lastNumber = lastNumber + 1
	    return lastNoteChecker(lastNumber)
    }
    
}
let lastDate = lastNoteChecker(1);
%>
View last daily note: [[<% lastDate %>]]

Unfortunatly it always play out the note from yesterday, even if this doesn't exist. What can I change?

I did a second test, to see, if the function works. tp.file.exists(...) always return true, no matter if the file exist.

<%*
	for (let i = 0; i < 50; i++) {
	document.write( i.toString())
	  DateCheck = "JOURNAL/2024/"+ tp.date.now("MMMM", -i)+ "/"+ tp.date.now("YYYY-MM-DD dddd", -i)
	  document.write( DateCheck)
	  if (tp.file.exists(DateCheck)) {
	  document.write( ' True')
	  } else {
	  document.write( ' False')
	  }
}

   
%>

tp.file.exists is asynchronous, so you need to await it, see examples in docs

Thanks, this worked:

async function lastNoteChecker (lastNumber) {
    lastDateCheck = tp.date.now("YYYY-MM-DD dddd", -lastNumber);
    filePath = "JOURNAL/" + tp.date.now("YYYY/MMMM/", -lastNumber) + lastDateCheck + ".md"
    const fileExist =  await tp.file.exists(filePath)
    if (fileExist) {
	    return lastDateCheck;
	 }
  // Only check last 50 days
  if (lastNumber > 50) {
     return 0;
  }
    else {
	    lastNumber = lastNumber + 1
	    return lastNoteChecker(lastNumber)
    }
    
}
let lastDate = lastNoteChecker(1);
