Thanks for replay.

How do you start the process?
It requires at the never least to add a variable called timeL1 So that the timer can be set.
it looks like whats happening is that you’re not sending in the required variable.

See actually I am new for camunda, first time I am using camunda in my project. As per my understanding I am sending required variable from my Nodejs API.

Did you build this process yourself?
show exactly the code you’re using to start the process.
