after following the official tutorial for enabling detection rules (Detections (beta) | SIEM Guide [7.8] | Elastic), I get the following error: * *[action_request_validation_exception] Validation Failed: 1: api key name is required;* *
I see that you use pretty outdated Kibana, eight versions behind Elasticsearch. Generally, it's recommended to have your stack versions in sync, so I suggest upgrading Kibana to 7.15.2. Having different versions could cause all sorts of incompatibility issues. Also, please check if you have all the prerequisites, including xpack.encryptedSavedObjects.encryptionKey and xpack.security.enabled config opttions.
Thanks Dmitrii, I'll try to upgrade Kibana first. The reason I haven't done it in the first place is because ES and Kibana are installed on a Raspberry Pi 4 and the only version I managed to install was 7.7 with NodeJS 10.19.0 ver.
I don't know what would be the corresponding NodeJS ver. for 7.15.2?
