Errors when trying to create snapshot

Elastic Stack Elasticsearch
1

I created the repository by using this command:

curl -XPUT 'localhost:9200/_snapshot/backups' -d '
{
"type": "fs",
"settings": {
"location": "/opt/elasticsearch_backups",
"compress": "true"
}
}'

It ran successfully. Next, I try to run a snapshot via this command:

curator snapshot --repository /opt/elasticsearch_backups indices --older-than 1 --time-unit days --timestring %Y.%m.%d --all-indices --exclude ".kibana"

But it throws an error.

Pass --repository backups to Curator, not --repository /opt/elasticsearch_backups.
