I am facing the same problem for a few hours and I haven't found any help here on the comunity.
I am using a form to save data on a sharepoint list along with an attachment file regarding a user. I want some function that enables me to remove the attachment file stored in a record without deleting the record itself. I know I can do it through the form but my goal is to do it through a button which will update the filds of name to "dummy" and delete the attachment associated to the record. Using the Patch function I am able to update the fields to "dummy", however I have not find a way to delete the attachment associated to the record...
So far I have figured out that the record.Attachments is a table with four fields: AbsoluteUri, Display Name, Id and Value. If the record doesn't have any attachment this fields are blank. My goal is to delete this attachment from the Sharepoint using some function. Do you have any suggestion?
The remove function remove all the data and I just want to update fields (already I have done it) and delete the attachment file.
