Replace #!/bin/bash -eu with #!/bin/bash and "set -eu". Otherwise, the "-eu" is not picked up when you run the scripts manually using "bash script.sh".

This is also in our shell style guide: "Executables must start with #!/bin/bash and a minimum number of flags. Use set to set shell options so that calling your script as bash <script_name> does not break its functionality."
