Unable to Invoke Subscribers

EmmaBurns — Wed, 11 Sep 2019 10:06:00 GMT

Hi,

I keep running in to this error but I'm unsure as to what is causing it -

Internal : Failed to perform step 1 in Navigate Stage 'Click Job Collection' on page 'Job Wizard' - An event was unable to invoke any of the subscribers (Exception from HRESULT: 0x80040201)

My Navigate stage is to click on a button within an in-house piece of software. The button has been spied in UIA mode, and the actual Press action is being passed to the software as the next window appears, but BP doesn't seem to register this, and throws the error every time.

Could anyone point me in the right direction to resolving this?

Thanks,

Emma.

When doing this, prior clicking event, maybe is safe to check if the robot is attached to the object parent window of the combo box.Create a flag with false and a decision stage, if is attached/activated and then if Yes--do the click if No--retry. You can put a i++ stage to increase the value plus 1 and then to retry for e.g. 5 times till an error is to be thrown.

I'm definitely attached, but I have tried anyway and had no difference.

I also ran in to the same error message when spying - when I pressed highlight on an element that I use in an existing process, I got the "An event was unable to invoke any of the subscribers (Exception from HRESULT: 0x80040201)" error message, but the process runs through fine when passed to the Runtime resource.

I haven't seen this error in any of my other objects, only on this in-house software - could it be something to do with how it's built?

if there are Inputs/Outputs, maybe in Object Stage you can add a current value. Sometimes Object Stage requires different variables to run etc.

I managed to get around it by changing the action from a Click to a Press or the other way round.

Maybe try that?

I has the same issue and switching from "press" to "click" helped.
Thanks for the advice.

Hi Sanskar,

Have you tried to put a wait stage before this action. This exception message can occur if your target element has not loaded properly or if it's schema is corrupted somehow while deciphering the attributes. You can try to induce a small delay before this and check once.

Another thing can be that sometimes some actions may not be compatible with the element that you are trying to automate here. Can you try to change the element type from the application modeler once and see how it goes from there?

Hi Devneet,

Thanks for your reply and solution.

We already have dynamic wait stage added before the that navigate stage that is assuring that download bar should popup.
This is a intermittent issue.

In application modeler element type is Button(UIA).

Let me know if you have any other resolution in mind.

Thanks,
Sanskar

Have you tried changing the element type from Button(UIA) to something else and seen if that is working?
