I am trying to download/save the attachment for list if attachment is enabled for list and item contains attachments using CSOM. I try to load the item.AttachmentFiles and if any attachment is there then try to save.

However, I came across one site "https://<tenantName>.sharepoint.com/sites/appcatalog" AppRequest list. While trying to load item.AttachmentFiles I am getting error "Column 'Attachments' does not exist. It may have been deleted by another".

Even when trying to add Attach file from Sharepoint online. I am getting blank/empty page, nothing happened on click. and in console getting some error. PFA.

How can I tackle this situation? Should I change my condition and explicitly skip the "AppRequest list"? or is there any way I can load the attachments?

Please help. Thanks in advance!

    Hi @Yuvraj Patil
    Per my test, I can reproduce your error in my appcatalog.

    As far as I know, App Catalog is system created site used to upload and store app package not attachment files. We are unable to attach files to AppRequest list and there is no attachment files too. So you can change the condition and skip the "AppRequest list".
