need help in resolving AWS cloud formation deployment error "Received FAILURE signal with UniqueId"

[sapnas]

I am using AWS cloud formation template provided by ESRI  for ArcGIS Enterprise 10.9 base deployment.  I have encountered error on ArcGISEnterpriseAllInOneWaitCondition with status "Received FAILURE signal with UniqueId xxxxxxxxx". I have raised a ticket with ESRI premium service  and it has been stalled as the personnel assigned to my case doesn't have expertise to resolve it. He is keeping the ticket rolling by sending one email every day. I am reaching out to the Geonet community to see if any one has any insights on what is causing this error. There are no entries in cloud watch or cloud trail to trouble shoot it further. The error occurs right after the creation of EC2 instance.

Hi can you give an example of the plaintext formatting for the password in secrets manager? Is it {"mypassword"} or {mypassword} or mypassword or something else?

Hi - I went of guidance here. And interpreted: 

• Delete all default text from the input field before you type the password.

To mean it should just be mypassword (third option you have above).
