Why Is the Event Object Undefined in my onFormSubmit Trigger for Google Apps Script?

The error you're seeing usually happens when you run the function in the editor (or trigger it with the wrong setup) so that no event object is passed. Here are some points to check:

1. Manual Execution:
   When you click "Run" in the Apps Script editor, no event object is provided. The trigger is designed to pass the event object (with key namedValues) only when the form is actually submitted. To test, either submit the form or simulate an event object.

2. Trigger Setup & Function Name:
   Make sure that the trigger is bound to the function with the correct name. In your case, the function is named "onFormSubmit", but you mentioned having set the trigger to run "onFormSubit". A typo like that would cause a trigger function not to receive any event object.

3. Correct Trigger Type:
   Ensure that the trigger you set is the one provided for form submissions (not a time-driven one or a manual trigger).

If you make sure that the trigger is set up correctly and test by submitting the form rather than running the function manually, you should get the proper event object with namedValues.

Below is a revised code snippet with a comment reminder:

// Ensure this function name exactly matches your trigger's configuration
function onFormSubmit(e) {
  // Check that the event object is passed and has the expected property.
  if (!e || !e.namedValues) {
    Logger.log("No event object provided");
    return;
  }
  
  const info = e.namedValues;
  createPDF(info);
}

function createPDF(info) {
  const pdfFolder = DriveApp.getFolderById("1g58GUQLPjPonsHtxj5LlxyoDgXs5wj2R");
  const tempFolder = DriveApp.getFolderById("1Fkzf0xeZcedfq7BF2k3V4mn4Pz_LsXsv");
  const templateDoc = DriveApp.getFileById("1eOqom8SqhuDUpIqYEVum-EvQ09cVz2d_XCLcRNAz8jE");
  
  const newTempFile = templateDoc.makeCopy(tempFolder);
  const openDoc = DocumentApp.openById(newTempFile.getId());
  const body = openDoc.getBody();
  
  // Replace text fields, assuming the form provides these values.
  body.replaceText("{fn}", info['First Name'][0]);
  body.replaceText("{ln}", info['Last Name'][0]);
  body.replaceText("{bd}", info['Birthday'][0]);
  body.replaceText("{em}", info['Email'][0]);
  body.replaceText("{pn}", info['Phone Number'][0]);
  body.replaceText("{pv}", info['Province'][0]);
  body.replaceText("{cm}", info['Contact Method'][0]);
  body.replaceText("{lg}", info['Language'][0]);
  body.replaceText("{ts}", info['Type Of Service'][0]);
  body.replaceText("{cn}", info['Child Name'][0]);
  body.replaceText("{cbd}", info['Child Birthday'][0]);
  body.replaceText("{sr}", info['Services Required'][0]);
  body.replaceText("{stf}", info['Staff Requested'][0]);
  body.replaceText("{pri}", info['Priority'][0]);
  body.replaceText("{ref}", info['Referral'][0]);
  body.replaceText("{jc}", info['Jane Consent'][0]);
  
  openDoc.saveAndClose();
  
  const blobPDF = newTempFile.getAs(MimeType.PDF);
  pdfFolder.createFile(blobPDF).setName(info['First Name'][0] + ' ' + info['Last Name'][0]);
  tempFolder.removeFile(newTempFile);
}

By ensuring that the function is only triggered by an actual form submission and that the function name (and trigger configuration) match, the error should disappear.
