Upgrading ojs from 3.4.0.10 to 3.5.0.2 ERROR: PHP Fatal error: Uncaught ValueError: Path cannot be empty

[LiFan]

Describe the issue or problem
I’m conducting an upgrade test, migrating the system from version 3.3.0-10 to 3.5.0-2. The upgrades from 3.3.0-10 to 3.3.0-22 and then to 3.4.0-10 were successful; however, an error occurred when upgrading from 3.4.0-10 to 3.5.0-2.

Steps I took leading up to the issue
Execute the upgrade command: php -d memory_limit=2048M tools/upgrade.php upgrade | tee -a upgrade.log

What application are you using?
3.4.0-10

Hi @LiFan,

This is caused by an upstream change at RoR; we’ve already filed and fixed it here. You can resolve it by applying this patch in the lib/pkp subdirectory, but we’ll also be releasing OJS/OMP/OPS 3.5.0-3 within a couple days, and it’ll include a fix for this.

I appreciate your prompt response. I’ll attempt to upgrade using a patch, and I’m also looking forward to the 3.5.0-3 release. Thank you again.
