`Undefined array key "key"` on Vapor due to Octane

Laravel Framework v9.43.0 Nova v4.19.5 ebess/advanced-nova-media-library v4.0.5

Issue: When I try to upload a file on my local machine to S3 without using octane, it works, but when deployed to Vapor running with Octane, the exact same code gets this error:

vendor/ebess/advanced-nova-media-library/src/Fields/Media.php:385 Illuminate\Foundation\Bootstrap\HandleExceptions::handleError

Undefined array key \"key\"

The file is saved correctly from the UI to the S3 tmp folder. The backend just can't seem to find the property in the $file var.

Commenting out the octane section fixes the error - but the app experience degrades.
