Rest API 409 Conflict Error

0

Hello,

At the moment I've split up a bigger project into smaller pieces so I can test out everything I need separately.

I'm trying to add a new attachment to an instance using this API /api/data/v4.0/db/{dbid}/elements/{id}/attachments. I have 2 fields into this form: contentBASE64 and fileName. All I'm trying to do is to use these values from my fields together with the API action so I end up with an instance in a final state having an attachment into attachemnts section.

I have already checked this post https://daniels-notes.de/posts/2023/copy-attachment-to-other-workflow as is probabily 75% or more from what I need to do, but still mine doesn't work. OAuth2 App is configured.. same as the connection.. same as the action. Everything looks fine but no. :)

Anyone have any idea how to sort out this little thing?

Thank you!
