Documentation of override Flow Config

[MirrahOH]

Hi everyone,

I'm currently trying to use the "Execute Flow" node in an AgentflowV2 Flow, to trigger a sub-flow, and I want to pass some data from the parent flow to the sub-flow using the flow state.

I saw there's an "Override Config" field, which seems like the right place to do this, but I haven’t found any documentation on how exactly it’s supposed to work. I've tried a few things through trial and error, but no luck so far.

Here are two examples of what I tried:

When I run it, I get this error:

{
"id": "executeFlowAgentflow_0",
"name": "executeFlowAgentflow",
"error": "AxiosError: Request failed with status code 500"
}
But when I leave the "Override Config" input empty, the node runs without any issues.

Here’s the schema of the sub-flow’s start node that I’m trying to address:

I'd really appreciate it if someone could point me to documentation on how to use the "Override Config" field correctly, or help me figure out what I’m doing wrong. Also how to adress the input form in the start node, would be interesting.

Thanks in advance! 🙏

Edit: Im running version Flowise 3.0.3.
