How to debug failed data transformations with your AI

Connect Coalesce to your AI client to stop digging through logs manually. Once connected, your agent can scan job metadata and node structures to find the root cause of a crash.

Short answer

How can my AI help me debug failed transformations?

Your AI reads job metadata and transformation node details to pinpoint where a pipeline broke. It identifies the specific error and the node responsible so you can fix it. You get a clear path to the solution.

Investigation outcomes

Where your findings land.

The AI sorts its findings into these four categories based on what it finds in the pipeline data.

LOG ERRORS

Identify broken logic

The AI pulls error messages from the job data. You get a plain explanation of the specific logic failure.

NODE ISSUES

Locate faulty nodes

The agent checks the transformation structure to find the exact step that failed. You'll know exactly which node to open.

SCHEMA DRIFT

Spot data mismatches

The AI compares node configurations to see if a schema change caused the crash. You get a report on the mismatch.

HUMAN ACTION

Manual fixes needed

The AI flags issues that require you to rewrite code or update settings. It tells you what you need to do yourself.

The workflow

What your AI does when a job fails.

Your agent takes over the tedious part of searching through logs and node hierarchies.

  1. Fetch job context

    The AI pulls the specific error logs and execution status for the failed run.

    get_job_details

  2. Map the pipeline

    It scans the transformation structure to understand how data flows through the nodes.

    list_nodes

  3. Correlate errors

    The agent matches the error message to the specific node that was running during the failure.

    get_job_detailslist_nodes

  4. Summarize the fix

    The AI provides a direct explanation of the failure and what needs to change in the node.

  • Why did job ID 55021 fail during the transformation step?

  • Look at the nodes in my last failed run and tell me which one caused the error.

  • Check the metadata for job 8829 and explain the error in plain English.

  • Compare the failed node configuration with the job details to find the mismatch.

FAQ

How this task behaves.

  • 01

    Can the AI fix the transformation for me?

    No. The AI only reads metadata and node details to find the problem. You have to make the actual changes in Coalesce.

  • 02

    Does the AI see my actual data values?

    No. The AI only has access to job metadata and the configuration of the nodes.

  • 03

    Can the AI trigger a new job run?

    No. This MCP is for inspecting existing jobs and nodes, not for executing new ones.

  • 04

    Can the AI delete a node if it's broken?

    No. The tools only allow the AI to read information. It cannot delete or modify anything.

  • 05

    Can I use this to debug a job from yesterday?

    Yes, as long as the job metadata is still available in your Coalesce history.
