    --name "detail-rule-1" \
    --event-bus-name "detail-bus-1" \
    --event-pattern '{ "detail": { "foo": [ { "exists": true } ] } }'

awslocal events put-targets \
    --rule "detail-rule-1" \
    --event-bus-name "detail-bus-1" \
    --targets "Id"="detail-target-rule-1","Arn"="arn:aws:sqs:us-east-1:000000000000:detail-sqs-1","InputPath"="$.detail"

awslocal events put-events --entries '[{"DetailType": "test", "Source": "aws.test", "Detail": "{ \"foo\": \"bar\" }", "EventBusName": "detail-bus-1"}]'
awslocal sqs receive-message --queue-url http://localhost:4566/000000000000/detail-sqs-1
