I am trying to copy the BOM and create new BOM and update the Name of the BOM with new data but for some reason record.copy is not returning any value, could you please help.

function(log, record, file) {

function getInputData() {
// Specify the internal ID of the CSV file in the File Cabinet
var fileId = ‘2196737’;
// Read CSV file content
var csvFile = file.load({
id: fileId
});

var csvData = csvFile.getContents();
var lines = csvData.split(/\r\n|\n/);
var headers = lines[0].split(“,”);

// Prepare data for creating new BOMs
var bomData = [];

for (var i = 1; i < lines.length; i++) {
var currentLine = lines[i].split(“,”);
var oldBom = currentLine[headers.indexOf(“oldBom”)];
var newBom = currentLine[headers.indexOf(“newBom”)];
bomData.push({
oldBOMId: oldBom,
newBOMData: newBom
});
}
return bomData;
}

function map(context) {
var entry = JSON.parse(context.value);
var oldBOMId = entry.oldBOMId;
var newBOMData = entry.newBOMData;

// Log old BOM ID and new BOM data for debugging
log.debug(‘Old BOM ID’, oldBOMId);
log.debug(‘New BOM Data’, newBOMData);

try {
// Copy old BOM
var newBOMId = record.copy({
type: record.Type.BOM,
id: oldBOMId,
isDynamic: true
});

log.debug(‘New BOM ID’, newBOMId);

// Emit new BOM ID as the key and new BOM data as the value
context.write({
key: newBOMId,
value: newBOMData
});
} catch (ex) {
// Log any errors that occur during BOM creation/modification
log.error({

});
}
}

}
