How to find a failure with each designer's debugging tools: the Omniscript Data JSON and Action Debugger, Action Message for chained Integration Procedures, the Flexcard action debugger's data source and action logs, Integration Procedure and Data Mapper Debug Log panels, and error logging to OmniComponentErrorLog records.

- Certification: Salesforce Omnistudio Developer
- Exam section: Troubleshooting and Debugging
- Study guide: https://www.certifyforce.com/study-guide/omnistudio-developer

**Official exam objective:**

> Use the Debug Console to identify failures and implement resolutions.

## What the exam expects

- Use the Omniscript preview Debug panel: read the Data JSON, search the Action Debugger, copy nodes and repopulate the console.
- Show a chained Integration Procedure's progress in the calling Omniscript with Action Message.
- Read the Flexcard action debugger: data source status and response, pubsub event logs (channel, event, inputMap) and set values logs (fields, response).
- Read Integration Procedure and Data Mapper Debug Log output in Preview.
- Keep a record of production Integration Procedure failures with error logging to OmniComponentErrorLog.

Key terms:
- **Data JSON**: the live JSON a component holds in Preview.
- **Action Debugger**: the console that lists each action's request and response in Preview.
- **Action Message**: step property whose text the calling Omniscript's Debug pane shows during chaining.
- **Debug Log**: the Preview output of an Integration Procedure's steps or a Data Mapper's queries.
- **OmniComponentErrorLog**: sObject that stores Integration Procedure errors when error logging is on.
