Users cannot log hours to a Jira ticket because unknown error message. Why? What is the solution?

[Lauren Pennisi]

Users with permission to a Jira project report that they cannot log hours either directly to a ticket or their Timesheets for Jira. They see this error:

Hi @Lauren Pennisi 👋

Since the error appears inside Timesheets for Jira, the quickest path is to contact that vendor’s support team — they’ll be able to check the cause of the logging issue.

If you need a working alternative in the meantime, you might want to try JetTime. It offers:

• Simple time logging with start/stop timers.

• Worklog reports filterable by project, user, or date range.

• Custom metrics and cost centers for billing or internal reporting.

• CSV/Excel export for finance or payroll.

• Privacy-first design — JetTime is built fully on Atlassian Forge and Runs on Atlassian, so data never leaves Jira Cloud.

Hi @Lauren Pennisi Lauren,

This issue usually happens due to Jira’s worklog permissions (missing Work on Issues) or time tracking configuration.

A practical fix is to use the Time & Cost Tracker for Jira (Timesheet | Budget | Reports) app, which simplifies time logging and avoids these errors. It provides:

• Easy logging from issues or a clear timesheet view.

• Validation to prevent invalid worklogs.

• Detailed reports with filters by user, project, or date.

• Export to Excel, CSV, or PDF for invoicing.

• Forecasting and cost tracking on top of worklogs.

It’s an all-in-one solution for logging, reporting, and managing worklogs.
