@Reddy, Lokanadh (Cognizant) Thanks for posting your question in Microsoft Q&A, apologize for any inconvenience caused on this.
Based on the above the error message, sync is failing due to host runtime is unavailable try to troubleshoot this.
I have looked at the backend logs of the function app "t3dev-ties-azf-app-01" and we see the functions were triggered and executed successfully.
If you are still facing issue, try troubleshooting the function app using the built-in detectors under diagnose and solve problems.
Hope this helps, let me know if you have any further questions on this.
