I had the same issue when I connected Botpress account to Stack AI. I fixed it my restarting the whole process and reducing the payload size. You can also use an API checker like Postman, to see if the delay is cased from their side. But again I'm not a developer by any means, you can post you issue in https://discord.com/channels/1108396290624213082/1111009377525186570, maybe someone more qulified can help you👍
