we have Jira charting plugin in use which created customfield "Time in status" and we see errors related to it in Jira log :
"automation-event-serializer:thread-2 ERROR" .... "More than one value stored for custom field id'customfield_15304'. Values [3_*:*_2_*:*_121506000_*|*_6_*:*_2_*:*_137527000_*|*_10003_*:*_1_*:*_13000, 3_*:*_2_*:*_121506000_*|*_6_*:*_2_*:*_137527000_*|*_10003_*:*_1_*:*_13000] "
what data should be in that custom field and any ideas how we could fix current errors ?
