Failed to calculate patch-ids (Rebase resets approvals)

After updating to 2019.07.03-bb5, PR-Booster no longer preserves approvals when "Automatically Withdraw Approvals" is set to "Yes - For significant pushes" after a server-side Rebase is performed. I don't recall exactly which version of PR-Booster was previously being used (possibly 2019.01.15), but server-side rebases prior to the update did preserve approvals.

The following stacktrace started appearing in atlassian-bitbucket.log following the update:
