Error handling issue

Posted on by empek

Hey there,

I'm trying to continue flow run when there is an error. But regardless all the settings for handling errors the flow will throw an error and terminate. I tried multiple options like skipping to the next step or to the label, but flow is stopped each time.

Why the option to continue flow is not effective.

Do you have any suggestions?

This is the error message that I'm getting.

And this is one of the configurations for "Get details of the page" component.

Hi @empek

The error in the first screenshot is a compile time error and not a run-time.

Meaning, it is an error shown by PAD saying that you have an incorrect browser instance parameter in the Get Details of web page action.

Give the correct browser instance variable coming from the Launch chrome/edge action and it will not occur.

If its still showing problems please share the screenshot of the entire flow along with the parameters given in the "Get details of web page" action.

Hey @VJR,

Great help. Thanks for that. That make so much more sense that this is the compile time error. This explains a lot, so thanks again for this clarification.

This is the PAD script:

Display.InputDialog Title: $'''Please enter URL''' Message: $'''URL''' InputType: Display.InputType.SingleLine IsTopMost: True UserInput=> URL ButtonPressed=> ButtonPressed WebAutomation.LaunchEdge.LaunchEdge Url: URL WindowState: WebAutomation.BrowserWindowState.Normal ClearCache: False ClearCookies: False WaitForPageToLoadTimeout: 60 Timeout: 60 BrowserInstance=> EdgeBrowser ON ERROR LaunchEdgeError SET correctURL TO $'''FALSE''' THROW ERROR ON ERROR InvalidUrlError SET correctURL TO $'''FALSE''' ON ERROR GOTO Jump END WebAutomation.GetDetailsOfWebPage BrowserInstance: EdgeBrowser DetailsType: WebAutomation.DetailsType.Title Details=> WebPageTitle ON ERROR GOTO Jump END IF IsEmpty(WebPageTitle) THEN SET correctURL TO $'''URL is not loading''' ELSE SET correctURL TO $'''URL loading correctly ''' END LABEL Jump Display.ShowMessageDialog.ShowMessage Title: $'''Message''' Message: correctURL Icon: Display.Icon.Information Buttons: Display.Buttons.OK DefaultButton: Display.DefaultButton.Button1 IsTopMost: True ButtonPressed=> ButtonPressed2

It is a simple exercise to build URL checker to see if the website is loading.

In the Step 3 of the flow, I'm getting the details of the page. Because I found that in the scenario when the DNS is not resolved correctly is not the same as "Invalid URL" parameter in PAD.
On a side note, do you know maybe some examples of "Invalid URL", unfortunately I can't find any it in the official documentation?
Then I'm using captured details to determine if the webpage loads or in case the URL was not resolved, because for this scenario script can't capture any webpage details. I'm doing that through "If Else" statement - Steps 4-8.
The scenario that I'm still failing to figure out is when the user provides URL that is not an URL format. Like
testing123 testing123
With this input as above I'm getting a Runtime error. Regardless error handling settings for "Lunch new Microsoft Edge" and "Get details of webpage" components.

Thanks again for all your help!

@empek

You can check if this suits your purpose

Use the Recognise entities in text action and select URL in the dropdown

If %RecognizedEntities.RowsCount% > 0 then it detects it as a URL.

Nice tip @VJR. This is a smart workaround. I was thinking to build a logic to check the URL before launching Edge instance, so your suggestion is extremely helpful. Thanks!

Ok, and if the Recognise entities does not capture all URLs correctly then Regex is your best option.
