Instance not starting up with saved ami id.

[anjaliagarwal8]

I started a session and setup the environment in the instance for deploying the model. After testing the code I stopped the instance (not terminated it), saved the ami id and updated the blueprint. When I again tried to use the same ami id to start the instance after a while it said, ami id does not exist.

I used this command too,
neurocaas-contrib remote start-devinstance
Instance i-0d5f45f10dd323cd4 is stopped, not safe to test.

I tried with the earlier ami id but it just started a new fresh instance. Can you please guide me on how to start the instance on which I was working?
