Unable LIST secrets

I have keys on path /v1/sys-kv2/data/secrets. The problem is that I can’t list via curl:

curl -k -v -H "X-Vault-Token: <>" -X GET https://localhost:8200/v1/sys-kv2/metadata/secrets | jq

I get:

< HTTP/2 404 
{
  "errors": []
}

Policy associated with token:

path "sys-kv2/*" {
  capabilities = ["list","read"]
}

Give this one a try:

curl -k -v -H "X-Vault-Token: <>" -X GET https://localhost:8200/v1/sys-kv2/metadata/secrets?list=true | jq

I got the same answer:

< HTTP/2 404 
{
  "errors": []
}

Did you use the example from this documentation: KV - Secrets Engines - HTTP API | Vault | HashiCorp Developer

Yes, exactly according to the instructions. Both versions v1 and v2 give the same answer as I mentioned above.

Does not seem you have key value in the metadata,

Do you have key value in metadata? then use this

curl -X 'GET' \
  'https://localhost:8200/v1/sys-kv2/metadata/secrets' \
  -H 'accept: application/json' \
  -H 'X-Vault-Token: hvs.fgkg' | jq

If you dont use this

curl -X 'GET' \
  'https://localhost:8200//v1/sys-kv2/data/secrets' \
  -H 'accept: application/json' \
  -H 'X-Vault-Token: hvs.fgkg' | jq

Yes, with the GET method, it returns a list of keys and values correctly. But I really want to use LIST to return a list without values.

To get only the keys without values, use this:

curl -X 'GET' \
  'https://localhost:8200//v1/sys-kv2/data/secrets' \
  -H 'accept: application/json' \
  -H 'X-Vault-Token: hvs.fgkg' | jq -r '.data.data | keys[]'
