UI error messages explained

Something went wrong. Check if the ics link is correct.

Shown when the user tries to add an invalid ICS link.

Verify the URL ends with .ics, opens or downloads in a browser, and isn’t behind auth. Paste a fresh link and try again.

Access denied. Contact calendar administrator.

Shown when a user with view-only access tries to move a non-Jira event (NJE) on the grid.

Ask the calendar owner to grant Edit access or perform the change on your behalf. Refresh after permissions change.

Introduced dates are incorrect, double-check them

Shown when creating or editing NJE if Ends on is set earlier than End.

Set a logical order: Start ≤ End ≤ Ends on (for repeats). Check time zones if values seem correct.

You don't have Reminder for Jira installed on your instance. Please contact your Jira administrator to have it set up.

Shown when toggling the Reminder integration on an instance where the Reminder for Jira app is not installed.

Ask a Jira admin to install/enable the Reminder for Jira app. After install, reload the page and re-toggle.

Can’t move recurring event. To change the start date of a recurring event you need to edit the event.

Shown when attempting to drag a recurring NJE; start date changes must be made via the event editor.

Open the event editor → edit the series (or the selected occurrence) → update the start date → save.

An error occurred while saving settings

Shown if saving changes to the calendar fails.

Retry once; if it persists, reload the page. Check required fields and network.

Unable to place the Jira issue on the calendar grid because the required date fields are missing from the issue screen.

Shown when dragging an issue from Unplanned issues to the grid but the project’s issue screen lacks the required date fields.

Ask a Jira admin to add the required date fields to the project screen (e.g., Start/End/Due). Try again after the screen update.

You don’t have permission to edit issues

Shown when user without the Edit issues permission:

• attempting to move the issue on the calendar grid;

• attempting to move the issue from Unplanned issues to the grid;

• dragging/resizing an issue on the grid;

• trying to place Existing issue onto the grid.

This is a definitive permission failure.

Contact the project admin to grant Edit issues or ask someone with that permission to make the change. After the change, refresh and retry.

An unexpected error occurred. Check if you have the required permissions and try again.

Shown when placing an existing issue on the grid fails and the user may lack Edit issues permission.

This is not strictly a permission error — permissions are one possible cause alongside network, validation, or server errors.

First confirm you have Edit issues. If you do, retry, clear cache/reload, and check required fields/values. If it persists, contact support.

You don’t have permission to delete issues

Shown when attempting to delete an issue from the grid without the Delete issues permission in the Jira project.

Ask a project admin for Delete issues or use a workflow that avoids deletion (e.g., transition) if deletion isn’t allowed.

Request timed out after 5000ms.

Shown when a request exceeds the 5000 ms timeout limit.

Check your network, retry the action, and avoid batching heavy changes. If recurring, report it with time and action details.

The issue(s) {issueKey} were created but cannot be displayed. This might be due to the calendar's JQL scope or your Jira permissions.

Shown when issues are created from the grid but cannot be shown—typically because they fall outside the calendar’s JQL scope or the user lacks permission to view them.

Verify the calendar’s JQL includes the new issues and you have Browse permission. Adjust JQL or permissions, then refresh.

Database error occurred while deleting calendar

Shown when rapid/repeated calendar deletions trigger a database error during deletion.

Wait a moment, refresh, then delete again. Contact support if it persists.

You have reached the maximum number of favorite calendars. To add this calendar, please remove one from your favorites.

Shown when attempting to add an 11th calendar to Favorites (limit is 10).

Remove a calendar from Favorites, then add the new one.

Couldn't connect to the {icsName} ICS link. Please remove it in the calendar settings to continue using other ICS links as usual.

Shown when an existing ICS connection is lost and the user tries to save changes; instructs removing the failing ICS to proceed.

Remove the failing ICS, save, then re-add it with the correct URL/credentials. Check that the source is reachable.

Something went wrong

Shown when replacing an existing ICS with a duplicate (already added) and clicking Save tab settings.

Remove duplicates. Keep only one entry per ICS source.

Failed to update embedded dates for the new issue.

Shown when creating a new issue from the grid/sidebar succeeds but updating embedded date fields fails because the user lacks Edit issues permission (has Create issue only).

Ask for Edit issues permission or open the issue and have someone with access set the dates.

An unexpected error occurred

Shown when a user with Delete issues permission lacks a required project role or other network, validation, or server errors, leading to an unexpected error.

Confirm required roles and project permissions. If everything seems fine, you can clear cache/reload. If it persists, contact support.

This event uses date-only fields. It must remain in the all-day section and can't be moved to the time grid.

Shown when attempting to move an all-day item that uses date-only fields from All day to the Time grid (Day/Week) view.

Keep it in All day or change date type your calendar is based on.

The value in "End" cannot be greater than the value in "Ends on"!

Shown in the NJE create modal when End > Ends on and the user clicks Save.

Set ‘Ends on’ to be greater than or equal to ‘End’.

Jira issues can't be moved to/from custom events or external calendars.

Shown when attempting to drag Jira issues into or drag items out of External calendars, Custom events, or Reminders rows in any Timeline view.

Move Jira issues only between “Resources” lanes that represent Assignees. ICS events, NJE events, and Reminders are fixed to their own lanes and can’t be moved across lanes.
