Hello Suhani_Bhatt.
Hope you are well!
Did you copy your production URL from your MCP server and paste it into your MCP Client?
Check this information and see if the URLs are copied correctly, whether they are production URL or test URL (as you wish).

Best regards.

Yes I tried both URL’s , test and production but getting same, error, when I make my workflow active I think then I will have to use production URL am I right?

Oi, desculpe a demora. No Brasil foi feriado de 4 dias, então não estava online.
Sim. Quando entrar em produção precisa colocar a URL de produção.
Deu certo, funcionou?

I have the same issue! Please help!!! @interss @Suhani_Bhatt
