Warning in log file "Could not chain"

Hello,

I see in a log file named "db_PX..." a lot of error : [Activity Chaining] Could not chain to attended activity.  No attended activity with compatible assignment was found."

but the related process seem working fine and I do not see any specific. The process is called by a webAPI and the result of the process is returned as result by the WebAPI.

The process is very simple.

The sub process called is

Have you already received a similar warning ?

I suspect the complex gateway.

Regards

I think this is expected. The original idea of chaining was to forward the user in the UI to the user input task. Now, in such a scenario, the chain ends without any.

Is it the chain from the timer to the timeout node?  Why would a chain ever successfully originate from a timer event?  It's not a user hoping to not get dropped.

The process is under a Web API, the chaining is required to return the value calculated by expressions in the script activities even if the timeout is triggered

Do you mean, you are using the process variables in the parent rule using fv!processInfo ? If not, then you don't need chaining because the sub-process runs synchronously.
