Question: Why do some GitHub Actions steps intermittently have no logs (data-log-url) after completion? #26175

Hi,

We are seeing an intermittent issue in GitHub Actions:

During execution, logs stream normally
After completion, some steps cannot be expanded and have no data-log-url
This happens inconsistently (same workflow, same code, different outcomes)

So our question is:

Under what conditions does GitHub Actions persist step logs and generate a data-log-url?
What could cause a step to have visible logs during execution but no logs available after completion?

Any clarification would be appreciated.

Thanks!
