Unattended flow can't login to website

Posted on by Community Power Pla... Microsoft Employee

I have a desktop flow set to perform these operations:

1. Open a new chrome window to website

2. Populate text field (username)

3. Populate text field (password)

4. Press button (login)

5. Wait for web page element (an element that appears after the login is successful)

When I run this flow attended from desktop, it has no issues and logs in then proceeds with the next action. But when I run my cloud flow which is set to run the flow at a scheduled time in unattended, the browser launches, and from what I can tell the username and password are input but then it will just wait forever, unable to execute step 5, making me think that for some reason after clicking login it's not authenticating and redirecting.

Any ideas how I can troubleshoot what's going on here? Thanks in advance.

Hi @eloomis ,

I ran into this issue when I encrypted my PW that I created on my local machine (same issue, runs great on attended but won't on unattended). Please login into your VM that is running this unattended flow, open it up on that machine and re-enter your PW and encrypt. This has worked for me. Please let me know if this works for you - always glad to help! Tom

The best way to resolve any UI automation issues on unattended flows is to add some Take screenshot actions, so you know what happened. We normally add those on error and also on some important steps.
I would suggest making the Wait for web page content action throw an error on timeout and then have a Take screenshot action in a separate sub-flow that you could call when an error occurs (via an On block error action).

When your flow fails, you can then check the screenshot to see what the page looked like at that point. This will help you figure out where to look further for the issue.

Thanks I'll try this. I have built in several conditional loops to handle my suspicions about the issue, but this will help me pinpoint what's actually happening.
