I went to @karol's initial diff where this code was introduced (D4216) and ran the Test Plan he noted there. Specifically, I ran:
```
cd services
yarn run-integration-tests backup
yarn run-integration-tests blob
yarn run-integration-tests all
```
However, all these failed.
I also checked out a new branch off `origin/master` and the same command failed in the same fashion. So it doesn't have to do with the code in this diff, this diff is purely for ShellCheck purposes. But we should definitely figure out what's going wrong there.
