The undeploy operation is executed properly by DCAE but it failed to be refreshed properly by CLAMP.

Comment from Vijay:
Vijay(12:07:34 AM): i can see query on Deployment handler for get which is failing bcoz the execution id is not longer valid in DCAE
 
Possibly Clamp does query DCAE but it can't answer anymore because this is not valid,
may be the workflow 'UNdeploy" should be revisited
 

Workaround:

Re-open the Loop again and the DCAE undeploy should be fine
