Traversing array not working

Traversing array not working: a task in MiMo-V2.6-RL-harbor-code: MiMo-V2.6-RL Code (Harbor) (Harbor dataset). In v2.2.0, a single imageSharp field is created on the top level of PictureCollection instead, with a value of null . There does not seem to be a possibility to query the downloaded images.
