## 📓 Summary Closes #151700 As shown in the video on [this comment](https://github.com/elastic/kibana/issues/151700#issuecomment-1497246729), the issue was reproduced when jumping to the lowest possible edge of the available logs in the lateral timeline. In case there are no existing logs before the selected time cursor, the `topCursor` value required for the previous logs call is set to `null` and the error was triggered. I believe in this case the conditional to trigger the error should not only rely on the missing `topCursor` variable existence, but we should also check whether previous logs exist with the `hasMoreBefore` state value. These are the conditionals in order of execution: - Top cursor missing but has more previous entries ➡️ trigger the Error - No more previous entries and the request is not forced ➡️ Short circuit data fetching - Top cursor exists => Trigger the request for previous entries. These changes also spotted an existing bug where the `hasMoreBefore` was never set to the API response value, but was always `true`, preventing also showing the "Expand time range" call to action on the scenario described above. ## 🧪 Testing - Navigate to Logs stream - Jump to a point in time that has no logs previously ingested - Verify the error is not logged when scrolling and that the "extend range" button is shown https://user-images.githubusercontent.com/34506779/230292210-c2690c37-efa1-4b05-a237-f14eb78d26eb.mov --------- Co-authored-by: Marco Antonio Ghiani <marcoantonio.ghiani@elastic.co> Co-authored-by: Carlos Crespo <crespocarlos@users.noreply.github.com> |

Getting Started
If you just want to try Kibana out, check out the Elastic Stack Getting Started Page to give it a whirl.
If you're interested in diving a bit deeper and getting a taste of Kibana's capabilities, head over to the Kibana Getting Started Page.
Using a Kibana Release
If you want to use a Kibana release in production, give it a test run, or just play around:
- Download the latest version on the Kibana Download Page.
- Learn more about Kibana's features and capabilities on the Kibana Product Page.
- We also offer a hosted version of Kibana on our Cloud Service.
Building and Running Kibana, and/or Contributing Code
You might want to build Kibana locally to contribute some code, test out the latest features, or try out an open PR:
- CONTRIBUTING.md will help you get Kibana up and running.
- If you would like to contribute code, please follow our STYLEGUIDE.mdx.
- For all other questions, check out the FAQ.md and wiki.
Documentation
Visit Elastic.co for the full Kibana documentation.
For information about building the documentation, see the README in elastic/docs.
Version Compatibility with Elasticsearch
Ideally, you should be running Elasticsearch and Kibana with matching version numbers. If your Elasticsearch has an older version number or a newer major number than Kibana, then Kibana will fail to run. If Elasticsearch has a newer minor or patch number than Kibana, then the Kibana Server will log a warning.
Note: The version numbers below are only examples, meant to illustrate the relationships between different types of version numbers.
| Situation | Example Kibana version | Example ES version | Outcome |
|---|---|---|---|
| Versions are the same. | 7.15.1 | 7.15.1 | 💚 OK |
| ES patch number is newer. | 7.15.0 | 7.15.1 | ⚠️ Logged warning |
| ES minor number is newer. | 7.14.2 | 7.15.0 | ⚠️ Logged warning |
| ES major number is newer. | 7.15.1 | 8.0.0 | 🚫 Fatal error |
| ES patch number is older. | 7.15.1 | 7.15.0 | ⚠️ Logged warning |
| ES minor number is older. | 7.15.1 | 7.14.2 | 🚫 Fatal error |
| ES major number is older. | 8.0.0 | 7.15.1 | 🚫 Fatal error |
