[BUG] V15 - Backoffice: Log Viewer date filtering not working

[andrejd22]

Which Umbraco version are you using?

15.4.1

Bug summary

Filtering logs by date does not work in the Log Viewer.

Specifics

When using the Log Viewer, setting the From and To date fields has no effect — the logs are not filtered based on the selected date range.

Additionally, after setting a custom date range, if you change the log level filter (e.g., to Error), the date range in the request payload reverts to the default values:

From: yesterday

To: today (i.e., the default range when first opening the Log Viewer)

Steps to reproduce

• Navigate to the Settings section.
• Open the Log Viewer.
• Set a custom From or To date in the date filter.
• Observe that the logs are not updated — the filter has no effect.

Expected result / actual result

When setting a From and/or To date in the Log Viewer, the logs should be filtered accordingly to match the selected date range.

Hi there @andrejd22!

Firstly, a big thank you for raising this issue. Every piece of feedback we receive helps us to make Umbraco better.

We really appreciate your patience while we wait for our team to have a look at this but we wanted to let you know that we see this and share with you the plan for what comes next.

• We'll assess whether this issue relates to something that has already been fixed in a later version of the release that it has been raised for.
• If it's a bug, is it related to a release that we are actively supporting or is it related to a release that's in the end-of-life or security-only phase?
• We'll replicate the issue to ensure that the problem is as described.
• We'll decide whether the behavior is an issue or if the behavior is intended.

We wish we could work with everyone directly and assess your issue immediately but we're in the fortunate position of having lots of contributions to work with and only a few humans who are able to do it. We are making progress though and in the meantime, we will keep you in the loop and let you know when we have any questions.

Thanks, from your friendly Umbraco GitHub bot 🤖 🙂

Thanks @andrejd22 for reporting this issue.
It seems happened from v15.4.0-rc until now 16.0.0-rc3. I was not able to reproduce it on v15.3.1.
API to get log-viewer should be called: /umbraco/management/api/v1/log-viewer/log when the date changes
