Hello Vapi Support Team, I am experiencing a persistent "Invalid Key" error and hope you can help me resolve it. The Problem: Every time I try to run a test call with any of my assistants, the call fails with the error: Invalid Key. Hot tip, you may be using the private key instead of the public key, or vice versa. Troubleshooting Steps Already Taken: This error occurs even though I have performed the following steps multiple times: Created a "Minimal-Test" Assistant: I created a brand new assistant with only a one-sentence prompt, a standard OpenAI model (gpt-4o-mini), and a standard ElevenLabs voice. This minimal assistant fails with the same "Invalid Key" error. Deleted Old Connections: I have deleted all existing OpenAI and ElevenLabs connections in my Vapi account settings. Generated New API Keys: I have generated brand new, fresh API secret keys from both OpenAI and ElevenLabs. Created New Connections: I have created new connections in Vapi using these new, valid secret keys. Re-assigned Connections: I have ensured that the new assistant is correctly using these new connections. Since the error persists even on a minimal assistant with fresh keys and connections, I strongly suspect there might be a technical issue or a "stuck" configuration within my Vapi account. Could you please investigate this on your end?
