Hello, When I tried to copy value of the payload object , It can be copied just what is visible on the debug window. Since the value is too much , all of them cannot be seen on the debug window just ... seen in the end and I also cannot copy all.

You can change the length in settings.js but setting it too long will likely cause the editor to slow down. I think if you change the debug node to output to log, you will get the full thing as well but that isn't terribly convenient. I recently also had problems like this and ended up having to ou…

:slight_smile: And if anyone wants a uibuilder flow that will do that, let me know. (hint - no code and no subflow required).

OK, here is the REALLY simple one :slight_smile: However, it doesn't quite match E1cid's subflow - I'll do a better one tomorrow. Add a uibuilder node and give it a URL of debug. Deploy. (no other settings needed). Add an inject node configured as shown below connected to the uibuilder input. Inj…

OK, as promised, here is a more complete example of a debug page using uibuilder. [{"id":"38dea932ad8bf5b0","type":"group","z":"30fdd9a9702231b0","name":"uibuilder Node-RED debug page - with full output and copy (Read my description for details)","style":{"label":true,"fill":"#ffefbf","fill-opacity…

It is working perfectly , thanks for your help

I really must thank you for this. It's an awesome way to help with debugging rather large messages in a manageable and readable way. Being able to pack the entire msg in and get syntax highlighting and proper formatting is pure bliss.

Not a problem. But just to make things even better (as I'm using this myself now), here is an updated version that is more compact and lets you do things like toggle on/off the json block. [{"id":"38dea932ad8bf5b0","type":"group","z":"ff1a7711.244f48","name":"uibuilder Node-RED debug page - with fu…

It's like you read my mind I submitted an example flow awhile back with the eventual intention of creating something similar to this but I doubt the quality and feature set of mine would have be nearly as great as this. I would love to see it become an example flow that sticks around.

Or you could use this subflow to send the msg to a separate browser window, you can then copy the message.
