I am unable to delete attachments from SharePoint list records. When I click the delete button next to the file name, i get a Confirmation dialog asking me to confirm if its ok to send the attachment to the recycle bin. After clicking OK nothing happens. I have attached a screenshot of the error that shows up in browser dev console when you click the OK button in the confirmation dialog.
The error is related to the file being checked out / open by a user. I’ll add some error handling to this function in the next version to try to work around this issue and ensure it is successfully deleted even if a user has it open.
If the file is not open in a web page or in the desktop app you can try to delete the file again.
