After a Merge node, binary file is not found even though it’s in the input.
What is the error message (if any)?
This operation expects the node’s input data to contain a binary file ‘FileUpload0’, but none was found [item 0]
Make sure that the previous node outputs a binary file
Please share your workflow
I have a Webhook node that contains a binary file. After merging it with a Jira node, the merged data is sent to a Slack node for file upload. The binary file is shown in the input of the Slack node but when uploading it, it says binary file not found.
If I remove the Merge node and connect the Webhook to Slack directly, the upload works correctly.
I’m confused as to why it errors after merging. Any help is much appreciated.
Ensure to copy your n8n workflow and paste it in the code block, that is in between the pairs of triple backticks, which also could be achieved by clicking </> (preformatted text) in the editor and pasting in your workflow.
```

That implies to any JSON output you would like to share with us.
Make sure that you have removed any sensitive information from your workflow and include dummy or pinned data with it!
I believe you use “Append” mode in Merge. As a result the output has 2 seperate items - one from Jira and one from Webhook. When Slack tries to use data from the 1st item there is no binary file there as it is in the 2nd item.
I suspect you need to use “Combine” mode in Merge so that output contains only 1 item, which will consist of data from both - Jira and Webhook.
