Hi there, i think i get what you mean, you already pass the API Key but the error Authorization failed - please check your credentials is showing like this

i think it is a bug on the display, but as long as the API Key is correct, i think all is good, because i just tried on my own, even though they said my auth failed, i can still succesfully trigger the node, maybe you can try that and let me know

Thank you!
