I cannt save the process model. This always says.. "The Process Model is invalid."

Hi everyone,

I´ve a problem because I cannt save my process model. I was looking for a solution, but I didnt find it. Any suggestion?

I´ve check:

- The Rules (name and inputs) and process variables are using correctly.

- The escalations in Tasks (I dont use escalations).

- Interfaces. Check the number and type of variables.

NOTE: I´ve more versions of the process model, but it always show the same message.. "The Process Model is invalid."

Thanks for your time,

Pablo.

  • Can you try to keep deleting nodes and attempt to save again each time you delete one? There is likely something in one of the nodes - I've mostly seen it with a reference to a process variable or activity class parameter that has been deleted. Eventually, you should delete one node that will then allow you to save it.

    Also before you do this, I'd recommend copying all the nodes to another process (it can be an empty one), because then you can copy any nodes back after making your changes.

    There's a small but severe caveat to this - if any node has an output expression that takes up multiple lines (i.e. has any linebreaks at all), and it's copied into a process model where that expression's output PV doesn't exist, everything after the first line of the expression will be cleared upon pasting.  This is an issue that I'd be happy if Appian fixed, though I have no reasonable expectation of that happening anytime soon, as it's been around for years as far as I've seen.
