Tool execution returning "An unexpected error occurred"
We are seeing "An unexpected error occurred." in tool executions, in a call detail, but when debugging the tool execution in our own API (the tool is a webhook to our API), POST was successful.
This is the call:
{
"toolName": "xxxxx-send-to-ringba-sd",
"startTime": "2025-08-13T20:22:30.893Z",
"toolCallId": "call_MIvDSuDIWYBC8WcMSoNh9g57",
"toolResult": "An unexpected error occurred.",
"vapiCallId": "a06ab406-bbd5-46b4-925c-d94ff2ec05ae",
"toolArguments": "{}"
}
Whats happening? Whats that "An unexpected error occurred."? We dont return that error in our API. What failed? Is your system not doing properly the tools that fetch APIs?
