Hullo Frank.

Full playbook and full output, please!

Also, what AMI is actually selected, if any, and if none is selected, which AMI specifically did you expect to be select ed (which AMI ID)?

which AMI were you expecting your script to find? Region, ID?

6

Hullo Frank.

What specific AMI did you expect your code to find?

Did you manually locate that AMI in the available AMIs for that region?

I.e., do you know for a fact that the AMI you seek does exist and does match that search string? Please tell us the specific AMI ID that you think matches your search string.

Also, you have provided two different search strings - which one is being used by your code?

Regards, K.
