When a workflow job fails because of a bug in task code, you can often fix the code, publish a compatible release, deploy it to the same cluster, and retry the failed job. Tilebox resumes from failed tasks instead of rerunning completed work.

​
Confirm the fix is compatible

A retry can use the fixed release when the failed task and the new task registration are compatible. Keep these stable:
  • task identifier name
  • task major version
  • task input schema
Use a new major task version and submit a new job when the input schema or behavior is no longer compatible with the failed task.

​
Publish the fixed release

After editing the workflow code, publish a new release. 
tilebox workflow publish-release
For validation details, build locally first. 
tilebox workflow build-release --debug

​
Deploy to the same cluster

Deploy the fixed release to the same cluster that received the original job. 
tilebox workflow deploy-release --latest --cluster workflow-dev
The job cluster, release deployment cluster, and release runner cluster must match.

​
Retry the job

Retry the failed job. 
tilebox job retry <job-id>
Then inspect logs and spans to confirm the fixed task completed. 
tilebox job logs <job-id>
tilebox job spans <job-id>
