Failed process start (exceptions)
Exceptions are types of errors meant to help you debug a failure in the execution of a process.
Exceptions can be accessed from multiple places:
- Failed process start tab from Active process menu in FlowX.AI Designer.
- Process Status view, accessible from Process instances list in FlowX.AI Designer.

Possible sources
Exceptions type
Based on the exception type, there are multiple causes that could make a process fail. Here are some examples:
| Type | Cause |
|---|---|
| Business Rule Evaluation | When executing action rules fails for any reason. |
| Condition Evaluation | When executing action conditions. |
| Engine | When the connection with the database fails when the connection with Redis fails |
| Definition | Misconfigurations: process def name, subprocess parent process id value, start node condition missing. |
| Node | When an outgoing node can’t be found (missing sequence etc). |
| Gateway Evaluation | When the token can’t pass a gateway for any reason, possible causes:
|
| Subprocess | Exceptions will be saved for them just like for any other process, parent process ID will also be saved (we can use this to link them when displaying exceptions). |
