Hi!
Today I upgraded to Graylog 3.2.4 on our integration server and everything so far went smooth, but after starting the server, all dashboards show this error:
While retrieving data for this widget, the following error(s) occurred:
- Unable to perform search query: failed to parse date field [2020-03-26 12:38:24.392] with format [strict_date_optional_time||epoch_millis].
I moved from 3.1.2 directly to 3.2.4 or is there an upgrade path I missed?
I’m using ES 6.8.2.
Thanks.
