I referred to the below post

https://community.appian.com/support/w/kb/365/kb-1145-no-datatypemodel-was-found-for-any-of-the-following-ids-to-be-updated-ids-error-returned-during-application-server-startup

The entry for the specific id is there and it matches the URI. 

I did a checkpoint before shutting down my old instance. I also tried with ta Fresh Installation. 

I am still facing this issue. 

Can any one help me with this issue?
