If you are asking about a problem you are experiencing, please use the following template, as it will help us help you. If you have a different problem, please delete all of this text 🙂 TIP 1: select at least one tag that further categorizes your topic. For example `server` for APM Server related questions, `java` for questions regarding the Elastic APM Java agent, or `ui` for questions about the APM App within Kibana. TIP 2: Check out the [troubleshooting guide](https://www.elastic.co/guide/en/apm/get-started/current/troubleshooting.html) first. Not only will it help you to resolve common problems faster but it also explains in more detail which information we need before we can properly help you. **Kibana version** : 7.10.2 **Elasticsearch version** : 7.10.2 **APM Server version** : 7.10.2 **APM Agent language and version** : java 1.20.0 **Browser version** : Google Chrome 88.0.4324.182 (Build officiel) (x86\_64) **Original install method (e.g. download page, yum, deb, from source, etc.) and version**: docker **Fresh install or upgraded from other version?** **Is there anything special in your setup?** I'have not change anything **Description of the problem including expected versus actual behavior.

I remove docker volume and all right. I think it's index error. ---

For anyone else seeing this error: > "An error happened when trying to fetch data. Please try again" I fixed it by loading the Heartbeat index template, and then deleting any `heartbeat-*` indices. > **[Load the Elasticsearch index template | Heartbeat Reference \[8.11\] | Elastic](https://www.elastic.co/guide/en/beats/heartbeat/current/heartbeat-template.html#load-template-manually-alternate)**
