ElasticSearch Create Index, index already exists exception

Question

I am trying a simple new index on elasticsearch cloud with postman (elastic v.52) But i cant see this index in my control panel.

I also received an "index not found" exception when I tried to send a delete request to the server.

I do not know what I'm doing wrong. Any ideas ?

Delete request:
