I’m noticing that the output in `circleci tests run` seems a bit odd:

```auto
DEBU[2025-02-25T16:11:31Z] Attempting to read from stdin. This will hang if no input is provided.
[...]
DEBU[2025-02-25T16:11:31Z] starting execution                           
DEBU[2025-02-25T16:11:31Z] Received:

```

note truncated `DEBUG`. The docs seem to imply it should show up as `DEBUG ....` and `INFO ...`.

Hmm I think the “DEBU” thing has always been like that if i recall correctly…is the functionality not working as expected? I admit I could be misremembering though. If it’s not working as you expect, can you DM me a build link and I can take a closer look?

In the examples [here](https://circleci.com/docs/rerun-failed-tests/#verify-the-configuration) it shows up as `DEBUG` and `INFO`. Seems like a mistake?

In that example:

```auto
DEBUG[2023-05-18T22:09:08Z] Attempting to read from stdin

```

However, what I see is `DEBU[2025-02-25T16:11:31Z]` - maybe someone did a string format based on `INFO` and didn’t think about the fact that the number of characters could vary? I saw some other output that people posted in [https://discuss.circleci.com/t/product-launch-rerun-failed-tests-circleci-tests-run/](https://discuss.circleci.com/t/product-launch-rerun-failed-tests-circleci-tests-run/) and it seems like it’s been like that for a while?

I turned off debug mode once I got it working, so not super criticial, just seems kind of ugly to me? If anything, the full timestamp is probably not that useful / necessary.

Totally fair, i’ll see if we can get that fixed. Thanks for raising it.

Hi @sebastian-lerner

I still see stuff like

```auto
DEBU[2025-11-14T04:58:01Z] starting execution                           

```
