Common error messages
If you see a specific error message, find it in this list for quick guidance.
| Error message | Likely cause | Next step |
|---|---|---|
| "Field Service is currently not available in your account" | The user doesn't have a Field Service license assigned, or the app isn't installed in the environment. | Verify license assignment and app installation. |
| "Web resource method does not exist: FS.Contact.Library.Load" | A solution update caused a version mismatch in web resources. | Run Solution Health Hub and check for solution version conflicts. |
| "Combined execution time of incoming requests exceeded limit of 1,200,000 milliseconds" | The environment is experiencing high load or has long-running custom plugins. | Reduce concurrent requests and review custom plugin performance. |
| "The plug-in execution failed because no Sandbox Hosts are currently available" | The Dataverse sandbox service is temporarily unavailable. | Wait and retry. If persistent, check environment health in the Power Platform admin center. |
| "Installing Field Service on a CDS instance isn't supported" | Attempting to install Field Service on an unsupported environment type. | Ensure the environment has a Dataverse database. See installation prerequisites. |
Before you contact support
Try these steps to resolve or narrow down the issue:
- Check for known issues. Review the version history to see if a recent update introduced a known issue or behavior change.
- Run Solution Health Hub. Administrators can run diagnostic tests that automatically detect common configuration problems.
- Clear browser cache. Many schedule board and form loading issues are resolved by clearing the browser cache and cookies, then performing a hard refresh (Ctrl+Shift+Delete, then Ctrl+F5).
- Test in a private browser window. Open an InPrivate or incognito window to rule out browser extension conflicts.
- Check user permissions. Verify the affected user has the correct security roles (for example, Field Service - Administrator or Field Service - Dispatcher).
- Review system jobs. For issues with automated processes (agreements, workflows), select Settings (gear icon) on the navigation bar > Advanced Settings > System > System Jobs to check for failed jobs.
