[Bug]: Some traces appear at the end of projects

[jverre]

What component(s) are affected?

• Python SDK
• Opik UI
• Opik Server
• Documentation

Opik version

• Opik version: 1.3.1

Describe the problem

Traces logged to the same project with versions 1.3.0 and 1.3.1 of the Python SDK appear out of order.

Issue:

This is due to the fact that the SDK was using the Python package uuid7 to generate the unique ids that are used to sort traces in the UI. However this package has an issue with the way the ID is generated which caused issues when logging traces from both the Python SDK and the upcoming Typescript SDK.

Resolution

To resolve this issue, we moved to a new library called uuid6 that doesn't have the same issue as the previous library. This change was released in version 1.3.1 of the Python SDK.

If you have already logged traces with version <=1.3.0, we recommend logging traces to a new project so that new traces appear at the top of the page.
