Catalog Request stuck in "Requested" status and not able to procceed further

Hello All,

Suddenly our vRA7 set up is having issue with deployment. I requested the catalog item but it is stuck in "Requested" state.

I followed the below KB but not resolved.

https://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=2145735

Also, follow the below link,but also not able to resolved.

Blueprint status "In Progress" for over hours and Machine status is Requested on Managed machines interface

I found the below error " Cannot insert the value NULL into column 'VirtualMachineName', table 'vra.dbo.VirtualMachine'" in the model manager log.  Does this error relate to the issue ?

Not sure why this error came ? Can you please help me how to resolve this issue so that Request can proceed to next steps ( Building >> Provisioning > etc) ?

Please let me know if you need more details.
