Console logs not showing, plus browser window size affecting displayed logs

Is there an existing issue for this?

Describe the bug

I work with a vertical monitor, and my browser window height is often 2300+ pixels. I’m using the latest macOS with the Edge browser.

A few issues I encountered here, see below.

Question: is there a workaround when the dashboard is broken, to see these logs? I can start resources manually, but that requires setting up several env vars normally managed by Aspire. Thanks. Update: for .NET I can see the logs launching Aspire from VS Code, where I can switch .NET process. Unfortunately this doesn't help for Python/Node.js/etc. processes.

Issue 1: missing logs

There is a problem around the 2250-pixel height threshold. If the window height is less than 2250 pixels, console logs display all lines correctly (more or less). However, if the height exceeds this threshold, the content is truncated after a few lines, and the rest is missing. Here are two screenshots of the same log, see around lines 100:

In a "regular" size window, when scrolling, the last log entries often disappear.

Issue 2: logs don't refresh

Even when using a smaller window size, new log entries do not appear. I have to refresh the page manually to see them.

Issue 3: incorrect scroll size

Not a major issue, but likely related: there’s an exaggerated amount of empty space after the last log entry, as if the viewport size or state calculation is incorrect. The extra space isn't always present; it appears depending on the scroll position. It often shows up after scrolling to the top and then back down.

Expected Behavior

• Critical: all logs lines should be visible and remain visible even if scrolling
• Important: the log page should automatically show new entries (I believe this is the expected behavior)

Steps To Reproduce

@JamesNK @adamint any thoughts on this?

[dluc]

I'm available to test nightly builds or work directly with src code if that helps, I only need some pointers where to start. Fixing this would be really helpful

@dluc if you'd like to contribute, you would be more than welcome to!

is there a workaround when the dashboard is broken, to see these [non-.NET] logs

Not that I am currently aware of. You could try downloading the logs for a resource using the settings on the top right of the console logs toolbar, but if logs are failing to load at all, this will not work.

1 and 3) are likely styling issues in LogViewer. 2) is trickier, could you confirm that this is happening in Safari too and for other aspire applications? Is there any error popping up in the console?

the problem disappeared, seems to be resolved - I'll reopen if needed

The issue is back, I can't think of a reason why, not that I changed anything particular... :-\
