Trouble creating files in user script

[Bencbabcock]

What I'm trying to do

I'm trying to create a template that creates a new note for each string in a list of strings that I paste into a prompt with a file name equal to that string using a user script

Things I have tried

This is the code I currently have:

// Define a function to create notes from lines of text
async function createNotesFromText(tp) {
    // Get the content 
    const fen = await tp.system.prompt("FEN Strings", "", true, true);
    
    // Split the input text into an array of lines using line breaks as the delimiter
    var lines = fen.split('\n');

    // Iterate over the lines and create a new note for each one
    lines.forEach((line) => {

        // Trim any leading or trailing whitespace from the line to ensure a clean title
        const noteTitle = line.replace(/\//g, '-').replace(/\s\d+\s\d+$/, '').trim();

        // Check if a note with the same title already exists
        if (!tp.file.exists(noteTitle)) {
            // Create a new note with the extracted title
            tp.file.create_new("", noteTitle, false);
        }
    });
}

module.exports = createNotesFromText;

This is resulting in nothing happening when I try to use the template, which contains this:

<%* await tp.user.chessPositionMassCreation(tp) %>

Just for reference, the list of strings are FEN notated positions in chess, such as these

rnbqkbnr/pppppppp/8/8/4P3/8/PPPP1PPP/RNBQKBNR b KQkq e3 0 1
rnbqkbnr/pp1ppppp/8/2p5/4P3/8/PPPP1PPP/RNBQKBNR w KQkq c6 0 2
rnbqkbnr/pp1ppppp/8/2p5/4P3/5N2/PPPP1PPP/RNBQKB1R b KQkq - 1 2

Any help would be greatly appreciated. Thanks!!!

This is solved now. I used "tp.file.find_tfile(filename: string) == null" and that solved the issue

tp.file.exists() likely wasn't working because it returns a Promise. You have to await it.

// using `await` to wait for result
const exists = await tp.file.exists(noteTitle);
if (!exists) {
  /* do stuff */
}

I like your workaround though!
