@stacey-gammon I think that looks more like a dashboard issue? I switched labels but please feel free to ping me if I am mistaken. Also this looks like it could be a potential blocker for 6.3.0?

[stacey-gammon]

Yep, looks like a dashboard issue. Investigating now to see if it's a blocker or not. As long as it doesn't kill the whole dashboard, even if the collapsed state of the legend isn't being saved, I think it's worthy to go into 6.3.1 but not a blocker.

[stacey-gammon]

I can't repro (at least on BC3 but nothing changed in dashboard from BC2 to BC3 that should have created this).

I'm opening/closing the histogram legend on the metricbeats dashboard and everything works.

@liza-mae - does it happen all the time for you?

[liza-mae]

ok - let me check it again and see

I have added another issue #18959 which shows when just isolated to the visualization, it throws two different TypeErrors.

As far as this issue it does not occur all the time, but when it does occur I do recall it stays in that state and is reproducible. I was not able to reproduce the exact error this time, but was able to catch the same error again which I notice only in dashboards, but this time it did not mess up the histogram. In dashboard: I see TypeError: Cannot convert undefined or null to object.

[stacey-gammon]

Can you walk me through what you are doing before you hit it? Just opening/closing the legend a bunch of times? Or do you have to open/close other dashboards, do anything else on the page?

I'll keep trying to repro on my end...

[liza-mae]

When the error occurred for me the first time, I just open/close the legend one time and saw the error. Once it was in that state it would continue to mess up even after I did a refresh to fix it.

Today when I went back to reproduce I did open/close a few times and only saw the error but it did not cause the histogram to mess up as it did the first time.

I am still on BC2 but I will also continue to try reproduce.

[liza-mae]

Sorry missed answering your other question, no other dashboards or browsers were open at the time, just metricbeat system one.

[stacey-gammon]

@liza-mae - Are you still able to easily reproduce? Can you trigger it with a simple bar chart histogram or only the metric beat one? Have you seen any more instances of it messing up a dashboard or only the console error?

If so, next time you run into it if we can zoom I can maybe look at the code in browser tools and see what the issue is.

[liza-mae]

@stacey-gammon I tried on BC6 was not able to get the dashboard to mess up on rendering, but I can still reproduce the TypeError in the console.
