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.
