Asset indexes utility throws error on Craft Cloud

[jamesmacwhite]

Description

When running an asset index on a Craft Cloud FS or Amazon S3 filesystem, the following error is logged after getting to the last asset item:

2025-05-19 06:03:46 [web.WARNING] [application] The assetindexdata table is empty; Can’t proceed with indexing. {"memory":9714456} 
sh: $'yii\rbacBaseManager': command not found

Seeing a shell error, potentially highlights where something might be going wrong:

sh: $'yii\rbacBaseManager': command not found

I can index the S3 volume without error on my local development environment.

Steps to reproduce

1. Run an asset index request for a Craft Cloud FS or S3 volume on Craft Cloud
2. The above error is logged after the indexing request reaches all asset items.
