How to pass binary data to subworkflow in n8n V2? The subworkflow can get binary data in n8n V1 by “When executed by another workflow“node. However, when I update n8n to V2. This node only receive a normal binary object, not binary.
What is the error message (if any)?
Please share your workflow

This is my “When Executed by another workflow” node
Hello Helios_Shao!
I have tried to use execute sub workflow and it works, just use expression in the image column that you want to send and enter {{binary.data}}
Hope this will be works for you!

Thank you for your reply, I have tried again. It works.
I understand the key is that if I want to pass binary to subworkflow. the node that output binary must directly connect with “Call subworkflow“ node
nice, great job, then can you mark my answer as the solution pls?
