Hi @PJStation,
thanks for reaching us. The 415 response is returned by Box API because of expiring_embed_link parameter used in fields parameter. If you remove this property, the response should be successful.
iOS SDK just returns response code returned by Box API. If you want to report a bug or propose an improvement for managing .conf files, you can reach Box support - https://support.box.com/hc/en-us.
Please let me know if removing expiring_embed_link from fields parameter helped.
Best,
@lukaszsocha2

Here is the list of the supported file types for the preview: https://support.box.com/hc/en-us/articles/360043695794-Viewing-Different-File-Types-Supported-in-Box-Content-Preview .conf file is not on that list.
Best,

it's worked!
I think expiring_embed_link can return nil and should not throw an exception in the list
