Unable to take snapshot - Version 5.6.12

Hello,
I was able to register the snapshot successfully. However, when I try to take a backup I'm getting this error message. "No matches found..." Any help is greatly appreciated.

Register Snapshot (works fine):
sudo curl -X PUT --cacert ${cacert} --key ${key} --cert ${cert} -H "Content-Type: application/json" https://localhost:9200/_snapshot/my_backup --data '{"type": "fs","settings": {"location": "/opt/xxx/xxxx/config/data/repository","compress": true}}'
{"acknowledged":true}#

Backup Command : (Does not work)
sudo curl -X PUT --cacert ${cacert} --key ${key} --cert ${cert} -H "Content-Type: application/json" https://localhost:9200/_snapshot/my_backup/snapshot_1?wait_for_completion=true

Error Message: 
zsh: no matches found: https://localhost:9200/_snapshot/my_backup/snapshot_1?wait_for_completion=true

Additional Information:

List Indices (work fine):
sudo curl --cacert ${cacert} --key ${key} --cert ${cert} 'https://localhost:9200/_cat/indices?s=index'

Welcome to our community! :smiley:

5.X is long past EOL, please upgrade as a matter of urgency.

That would suggest this is a shell issue, not an Elasticsearch one. Have you tried wrapping the url in quotes?
