History charts not showing or loading in v2.15.0

[cedric-kany]

Describe the Bug

The history chart of views and visitors is not showing in the new version of umami, neither in the dashboard nor in the details page. I have multiple pages connected to umami all having the same issue, there are no errors in the console or the requests and the "non-chart" data is showing fine. There might be an issue in the chart library?

Hi !
I didn't try that much, but spotted an issue which can surely be the culprit here:

In lib/prisma.ts, MySQL convert_tz expects a timezone to be in a +00:00 like format, which was correctly done with moment-timezone library.
It has changed in the transition to date-fns-tz => tz is now a 'full' date, and should cause NULL values to be returned because it's an invalid argument.

Should be fixed in v2.15.1.

Should be fixed in v2.15.1.

It has been fixed for me in v2.15.1
