Your JMESPath may very well be correct for one object but as its name implies, and as your debug: var=A.stdout_lines shows, stdout_lines is a list

So, you can do one of several things:

• recognize that your stdout_lines only contains one object and just feed that into json_query as {{ A.stdout_lines[0] | json_query(jmesquery) }}
• use the map filter to apply that same filter to every list item, with something like {{ A.stdout_lines | map("json_query", jmesquery) | list }}
• rewrite your JMESPath to apply that filter to the input list, akin to json_query("[*].configuration.AND THE REST HERE")

Those last two will naturally produce a different output shape, since they are lists of lists, and so it will look like [['ge-0/0/0']] when output, but they do have the advantage that if your stdout_lines ever does mysteriously start to contain more objects, they will be json_query-ied as expected
