Work Time Tracking Calendar for Jira v 7.1.x: After Jira upgrade to version 9.x.x worklogs for past periods are not shown

The problem is caused by Safeguards for Jira index that were introduced in Jira 8.22.2: Introducing Safeguards for Jira index .

To fix the problem set jira.safeguards.indexing.issue.worklogs in setenv.sh to MAX_WORKLOGS_YOU_HAVE_IN_ANY_ISSUE (I guess 50000 is sufficient for most real cases) and run the full re-index. After that you can put jira.safeguards.indexing.issue.worklogs back to 100 or what is acceptable for your business scenarios.

Kudos to Jira jql query for worklogdate does give wrong result after upgrade from 8.x to 9.4.3
