Getting Error While Trying to Save Process Model

Sowvik Roy
Certified Associate Developer

Please note that I am able to save and publish this successfully, which is very strange.

Here are the logs:

I had created this simple process model to identify the issue of a much bigger process model. There I had faced another issue, I had saved and publish the process model with no issues, but after refreshing the browser I can see the Escalation Events are "Unknown Event" as show in the screenshot below, but actual Events are present there I had selected those

    Can you explain your usecase and current Design? the description is quite confusing and missing major details like where is the send message configured, where is receive event configured, which model has errors, which publised successfully etc. Getting more details help with better solution suggestions. The logs don't have much to inform here so understanding the goal will help resolve it faster.
