Error handling for close web browser

(0) Share

Posted on by deerzzxdell

Hello community,

I have a flow that use action launch new Microsoft edge 2 times. After the flow ends or got any error, I use label to go to error handling and close webbrowser1 and webbrowser2.

But I found a problem with my flow that if the error happens in between when webbrowser1 is opened but webrowser2 hasn't, yet I will get another error.

So do you have any idea how I should change the error handing or if there's any way to check whether the webpage is open or not (not using if webpage contains)

@Chetan_Ninghot
thank you for the reply, so here's the code, The first thing I do is launch the edge (1st) and do some action and then launch another edge (2nd).

My problem is when there's an error happen during line 16 populate text field on web page, the flow will jump to label error handling in the picture to get last error.

In the region error handling, after getting last error into variables, it will close both browsers in line 106 and line 107. But what happen here is I got an error again at line 106 because there's only 1 browser that got opened.

And what I have shown you is sub flow. After this it will go out to main flow to check again whether there's an error during sub flow. By using the same code of error handling

I've look through action details in power automate cloud and see the result of each last error. The first on happen because it failed in line 16
"value": "Failed to write text in form field.",

For another one it failed in line closing web browser because PAD can't find browser2 (not open)
"localizedName": "Error",
"value": "Argument 'BrowserInstance' must be 'Web browser instance'.",

Also after all the flow ended the last error also got overwrite with the second error, it didn't show the what happen in the first place, so i have to go through Desktop flow action details on PA web

Hi,
Have you try Terminate process action (select process name is chrome)for closing you browser , it can closed you both browser if its open or its not open this action not through any error.
if nay error come if you want to stop process instead of going to main flow you can used stop flow action at end the error handling sub flow.
"value": "Failed to write text in form field.", if populate text field action failed you can select proper attribute of this element.

You can add a condition to check if the browser instance is empty. You can check if %Browser2% is not empty (it's empty if it's never been opened) AND if %Browser2.Handle% is not equal to -1 (it would be equal to that if the browser was opened, but was also closed already). If both of these are true, you use Close browser to close it. If either of these is false, you skip the action.
