Anybody else experience this error when trying to execute the a/b split test sequence from the build a Vapi cold caller bot ?

Hello everyone, I hope you are well? I want to integrate Whisper, the speech to text transcription API on voiceflow but I can't capture the value of file, can anyone help me please? THANKS

Wassup y'all! Grateful to be here, and shout out to Brendan, love your vids, helped me out a ton. I am wondering, has anyone successfully paired a cold caller campaign with SMS? For example, if an agent with VAPI talks to a person and the script asks, 'Can we send you some more info via SMS?', can we set up automation to allow VAPI to send texts directly? I have been launching some cold email campaigns and it has been hell navigating to avoid blacklisting domains wondering if SMS could be a nice segway.

Anyone using any voice caller platform other than these ones? 1.Vapi 2.Bland 3.Synthflow 4.Retell 5.Air AI
