I am testing red node API and flow function is not stable, sometime it works, some not. Let me explain

For some flow, [http://127.0.0.1:1880/flow/901cbcd3.2151d](http://127.0.0.1:1880/flow/901cbcd3.2151d) , this link work perfectly  
However, this node id "f7656a21.10d448" does not work (it exists in picture below)

So can anyone help me to find what is happening, thanks

Not sure what you are expecting this to do. That node is a ui\_button on the dashboard - it isn't a http endpoint - so there is no point browsing that url.
