Getting sporadic error when getting the active form - google-apps-script

Question

I am once in a while getting this error:
Jan 5, 2023, 11:03:48 AM Error Exception: Failed to retrieve form
data. Please wait and try again. at processForm(Code:2:22)
Line 2 is:
var form = FormApp.getActiveForm();
Full script
function processForm(event) {
var form = FormApp.getActiveForm();
Logger.log("Form retrieved " + form)
var allResponses = form.getResponses();
var latestResponse = allResponses[allResponses.length - 1];
var itemResponses = latestResponse.getItemResponses();
//const itemResponses = event.response.getItemResponses();
const propertyAddress = itemResponses[0].getResponse();
Logger.log("Processing address " + propertyAddress);
// Get the number of units. index 5
const moreThan200Units = parseInt(itemResponses[5].getResponse(), 10);
var mainFolder = null;
if(moreThan200Units > 199) {
mainFolder = DriveApp.getFolderById('xx');
} else {
mainFolder = DriveApp.getFolderById('yy');
}
var propertyFolder = null;
for (var i = 0; i < itemResponses.length; i++) {
Logger.log(itemResponses[i].getItem().getType())
if (itemResponses[i].getItem().getType() == "FILE_UPLOAD") {
if(propertyFolder == null) {
propertyFolder = mainFolder.createFolder(propertyAddress);
}
var ids = itemResponses[i].getResponse();
for (var j = 0; j < ids.length; j++) {
var uploadedFile = DriveApp.getFileById(ids[j]);
Logger.log("Moving file" + uploadedFile + " to " + propertyFolder);
uploadedFile.moveTo(propertyFolder);
}
}
}
