Can you please provide some more information about what exactly is not working? Is there some kind of error, does it execute fine but the request does not lead to the expected result, …? Would also be good to know how the endpoint you send the data to does expect the data.
Because n8n should execute just fine (just to be 100% sure did I tested, and no error).
Sorry but kind of just repeated again what you wrote before “it does not work” with a screenshot, you did not answer any of my questions. What does “it does not work mean”? For example, you say “my car does not work” but it is a big difference if you turn the key and nothing happens if you hear the engine turning around or a lot of smoke appears.
So if you execute the workflow does it:
display some kind of error message? If so what error message?
execute fine but whatever the request should do, does not happen (for example it does not send an SMS or whatever you want to do)
keep on loading and it literally never finishes?
does the whole UI freeze
none of them and it is something totally else?
Each of the above can still have multiple reasons each but we have to start to narrow it down to be able to help you.
