Self checklist (all need to be checked):

• The developer has manually tested the changes and verified that the changes work.
• Commit message includes a reference to the corresponding JIRA issue (eg. commit message: "ISPN-1234 JIRA TITLE...").
• Commits have been squashed and self-contained units of work (e.g. 'WIP' and 'Implements feedback' style messages have been removed).
• Testing instructions have been added in the PR body (for PRs involving changes that are not immediately obvious).
• The developer has added tests or explained why testing cannot be added.
• Included any necessary screenshots or gifs if it was a UI change.

The build is green. Merging for preventing the further nightly build failures.
