Invoke workflow arguments error

[Alex_Cross]

It is invoked within the Send Email state:

As shown here:

Understood, but you mentioned that its not going inside after it prints, “Emailing the PDF files”

[Alex_Cross]

Correct

[nadim.warsi]

Then your invoke is broken for some reason.
But im not able to understand in that case why does it not throw null reference or instance of error:roll_eyes:

[Alex_Cross]

I agree, it makes no sense, I have no idea what the Object error it complains about is as nothing seems to be “incorrect” as it works in isolation just fine.

[nadim.warsi]

Let me recommend something as a hit-n-trial.

Invoke the same workflow, just move your arguments to variables and default them.
Now refresh your workflow invoke(no arguments) and test. does it still fail?

You’re a hero, I know it’s a “botch job” but it works! Thanks so much for your time and help!

So I assume it must have been related to the invoke being buggy - anyone from UiPath have an idea? I copy and pasted the invoke which pulls in the config again, and created 4 A-B assigns which recreated the arguments as variables, which I think called for the rest of the component, otherwise it was identical.
