"Evaluation Errors" tab is broken for individual evals

[ruro]

Describe the bug

The "Evaluation Errors" tabs on jobset pages is working correctly (showing the evaluation errors for the latest eval of that jobset). For example, here is how it currently looks for the nixos/trunk-combined jobset (you might have to wait a second for the logs to load):

However, if you open the page for any individual evaluation of the same jobset, then the logs on the "Evaluation Errors" tab appear empty:

The same thing is happening on the nix-community hydra servers (jobset vs evaluation), so it doesn't seem to be a problem specific to the official Hydra instance.

Hydra Server:

I don't run either of these Hydra instances. Here is the information from the footers:

• hydra.nixos.org Hydra 0.1.20250216.c3b6e7b (using nix-2.24.8 and nix-eval-jobs-2.26.0).
• hydra.nix-community.org Hydra 3235ace (using nix-2.24.12 and nix-eval-jobs-2.25.0-unstable-2025-02-13).
