I've worked through previous posts with this error but cant find a solution. It has been working for 3 months without an issue and now has started either failing with Attachment content cannot be null or empty error or it says it is successful but sends the email without any attachments.
The flow emails attachments from a SharePoint library folder and then deletes the sent item from the users outlook. It was set up using this article Advanced | Flow of the Week: Send multiple attachments on a single email | Power Automate Blog (microsoft.com)
when it is says it is successful but no attachments it still deletes the email correctly so it is only the attachment section that is not working.
The flow hasn't been edited in this time and the SharePoint library hasn't had any changes made to configuration. the number of documents in the folder varies and can be a mixture of word, pdf, jpg but when it was working it was attaching all doc types correctly.
I have tried removing and re-adding the condition section and also adding a delay between the condition section and send email but it hasn't helped.
Has anybody had a similar issue and resolved it? Any help will be appreciated 😀
Edited to add - I have turned on the Flow that I originally created before sharing and its working properly - there is no difference in them at all.
