Before you change production

This page includes public source URLs in the imported troubleshooting record. Compare those references with your version and environment before applying changes.

Reproduce the smallest failing action and save non-secret logs before changing configuration.
Check versions for Azure, related SDKs, package managers, CI runners, and hosting providers.
Change one setting or dependency at a time, then rerun the same failing command or request.
Avoid destructive commands, credential rotation, billing changes, or security relaxations without a rollback plan.

What this error means

[BUG]: Long-running jobs lose authentication and fail at finalization — Azure Pipelines agent loses session token during extended execution is a Azure failure pattern reported for developers trying to azure pipelines jobs that run longer than expected (e.g., compilation, testing suites) silently lose authentication mid-execution and fail at the finalization stage, requiring investigation of agent timeout and credential refresh settings.. Based on the imported evidence, treat this as a tool-specific troubleshooting page rather than a generic API error.

Why this happens

GitHub issue microsoft/azure-pipelines-agent #5520 filed as open bug titled 'Long-running jobs lose authentication and fail at finalization'. MicrosoftDocs azure-devops-docs contains errors-workload-identity documentation covering workload identity authentication edge cases. Category: Cloud Platforms per mapping rules. Distinct from generic AADSTS7000222 — this is specifically about agent-level token loss during extended job runtime, not credential expiry.

Quick fixes

Confirm the exact error signature matches [BUG]: Long-running jobs lose authentication and fail at finalization — Azure Pipelines agent loses session token during extended execution.
Check the Azure account, local tool state, and provider configuration involved in the failing workflow.
Verify the account session, API key, provider settings, and environment where the failing tool is running.

Platform/tool-specific checks

Verify the command, editor, extension, or API client that produced the error.
Compare local settings with CI, deployment, or editor-level settings when the error appears in only one environment.
Avoid deleting credentials, local model data, or project settings until the failing scope is clear.
