Capture giving empty prompt

I am not able to correctly use voiceflow POST API to add items through voiceover or chat directly into Airtable. I tired using POST API templates shared by Voiceflow but the voice flow gets stuck in Capture stage giving empty prompt message.

You can refer to your own template of POST API. I tried replicating that but the template also had the same issue.

Please help as I want to build big project on voiceflow and I am not even able to start because of the issue.

Are you able to show how you have both step(s) set up?

Please check the below Capture screen Shot:


POST API config:


The same issue I faced in the Template. The link is given below:

I have shared the screenshots above for your reference.

Awaiting for response.
