The Frustrating Problem: Time-Driven Triggers Not Firing
Have you ever set up a time-driven trigger in your workflow, only to find that it’s not triggering as expected? You’ve double-checked the setup, triple-checked the syntax, and even quadruple-checked the timing, but still, nothing happens. It’s like the trigger is stuck in a time loop, refusing to budge.
The Culprit: GetActiveUser() Only Working on Owned By
The culprit behind this frustrating problem is the GetActiveUser() function, which, as its name suggests, retrieves the active user. However, it only works when the trigger is owned by the same user. If the trigger is owned by a different user or is set to “Anyone,” the GetActiveUser() function returns null, causing the trigger to fail.
Solutions to the Problem: Time-Driven Triggers Not Triggering
Don’t worry, dear reader, for we have not one, not two, but three solutions to this pesky problem! Try them out and see which one works best for you:
Solution 1: Change the Trigger Owner
The simplest solution is to change the trigger owner to the user who is supposed to trigger the workflow. This ensures that the GetActiveUser() function returns the correct user, and the trigger fires as expected.
// Change the trigger owner to the correct user
trigger.setOwner('[email protected]');
Solution 2: Use the GetTriggerUser() Function
Another solution is to use the GetTriggerUser() function instead of GetActiveUser(). The GetTriggerUser() function retrieves the user who triggered the workflow, regardless of who owns the trigger.
// Use GetTriggerUser() instead of GetActiveUser()
var triggeredBy = GetTriggerUser();
Solution 3: Create a Proxy User
The third solution is a bit more involved, but it’s worth it if you need more flexibility. Create a proxy user and set up the trigger to run under that user’s context. Then, use the GetActiveUser() function to retrieve the original user who triggered the workflow.
// Create a proxy user
var proxyUser = '[email protected]';
// Set up the trigger to run under the proxy user's context
trigger.setOwner(proxyUser);
// Use GetActiveUser() to retrieve the original user
var originalUser = GetActiveUser();
Additional Considerations: Time-Driven Triggers
Now that we’ve solved the problem of time-driven triggers not firing, let’s talk about some additional considerations to keep in mind when working with time-driven triggers:
Scheduling Conflicts
When using time-driven triggers, it’s essential to avoid scheduling conflicts. Make sure that the trigger is not set to run too frequently, as this can cause performance issues and even trigger failures.
Time Zones
Time zones can be a real challenge when working with time-driven triggers. Make sure to set the correct time zone for the trigger, and consider using UTC time to avoid any confusion.
Trigger Delays
Sometimes, triggers can experience delays, which can cause the workflow to fail. To mitigate this, set up a retry mechanism to ensure that the trigger fires even if it’s delayed.
Conclusion: Time-Driven Triggers Made Easy
There you have it, dear reader! With these solutions and considerations in mind, you should be able to get your time-driven triggers firing on all cylinders. Remember, getActiveUser() only works on owned by, but with a little creativity and the right solutions, you can overcome this limitation and create powerful workflows that automate your business processes.
FAQs: Time-Driven Triggers
Frequently asked questions about time-driven triggers:
| Question | Answer |
|---|---|
| Why is my time-driven trigger not firing? | Check the trigger owner and ensure that it’s set to the correct user. Also, verify that the GetActiveUser() function is working correctly. |
| What’s the difference between GetActiveUser() and GetTriggerUser()? | GetActiveUser() retrieves the active user, while GetTriggerUser() retrieves the user who triggered the workflow. |
| Can I use time-driven triggers with multiple users? | Yes, you can use time-driven triggers with multiple users by creating a proxy user and setting up the trigger to run under that user’s context. |
By following these solutions and considerations, you’ll be well on your way to creating powerful time-driven triggers that automate your business processes with ease. Happy automating!

Frequently Asked Question
If you’re facing issues with Time-Driven Triggers not firing as expected, you’re not alone! We’ve got the answers to your burning questions about getActiveUser only working on owned by.
Why are my Time-Driven Triggers not triggering at all?
The culprit might be the getActiveUser function, which only works when the script is running under the authority of the owner of the trigged sheet. If the trigger is not owned by the same user who sets it up, getActiveUser will return null, causing your trigger to fail. Try using getEffectiveUser instead, which works for both owners and non-owners.
What’s the difference between getActiveUser and getEffectiveUser?
getActiveUser returns the user who is actively running the script, whereas getEffectiveUser returns the user under whose authority the script is running. While getActiveUser only works for the owner, getEffectiveUser works for both owners and non-owners, making it a better choice for Time-Driven Triggers.
Can I use onOpen triggers instead of Time-Driven Triggers?
Yes, you can! onOpen triggers are a great alternative to Time-Driven Triggers, especially if you’re experiencing issues with getActiveUser. onOpen triggers fire every time the sheet is opened, regardless of who opens it, making them a more robust option.
How can I check if a Time-Driven Trigger is owned by me?
Easy peasy! You can check the owner of a Time-Driven Trigger by going to the Triggers page in your Google Apps Script editor. Click on the three vertical dots next to the trigger and select “Edit.” The owner’s email address will be displayed at the top of the trigger settings page.
What if I need to run a script as a different user?
That’s a great question! If you need to run a script as a different user, you can use service accounts or impersonation. Service accounts allow your script to run as a separate entity, while impersonation lets you specify the user under whose authority the script should run. Both options can help you overcome the limitations of getActiveUser.
