OpenProject Database Restoration Issue

I'm currently following all the steps outlined in the official OpenProject documentation for restoring a database: https://www.openproject.org/docs/installation-and-operations/operation/restoring/.

However, at the very end of the process, I'm consistently getting the following error:

root@ubuntu:~# sudo pg_restore --clean --if-exists --dbname $(sudo openproject config:get postgres://openproject:JeEGXpTUh0cmQ7htL09qe0fxapzr37Pk@127.0.0.1:45432/openproject) postgresql-dump.pgdump
sed: -e expression #1, char 15: unknown option to `s'

Any insights into what might be causing this sed error during the pg_restore process would be greatly appreciated!

Has anyone else encountered this same issue?

Thanks
