Describe the problem/error/question
I am building a Workflow, which does some OCR on Invoices and Files them to OneDrive following a specific naming schema. I am downloading Attachments from Exchange, doing the OCR and finally filing those to OneDrive. If I have more than 1 Mail, or more than 1 Attachment within a Mail, I process multiple items.
I was not able to access the binary Data from a previous Item, it always returned the first Binary data. Meaning if I have 2 Items, all 2 Items return the Binary data of the first Item.
This is how accessed the binary data:
As a workaround, I use now the messageId and attachmentId throughout my workflow and redownload the attachment before uploading to OneDrive. That way, it works. Main difference, as downloading again directly before uploading, is, I can access the binary data using
I was wondering, if it should actually work to access binary data of a previous node (in my example “Upload a file” node using the “download attachments”)?
thank you, stefan
What is the error message (if any)?
None, just accessing always the first binary data of the array of items.
Please share your workflow
Share the output returned by the last node
