URGENT: Cant save any workflow with API Request

No matter what, even in a new, otherwise empty workflow it says: Save Failed / Failed to save workflow: each value in nodes.tool.server.cerdentialId must be a UUID. Even working systems i cant save any changes on.

To resolve the "credentialId must be a UUID" error, create a Custom Credential in your Vapi dashboard and use its credentialId in your API Request node. Example configuration:

"server": {
  "url": "https://your-api-endpoint.com",
  "credentialId": "cred_abc123" // Replace with your actual credential UUID
}

"server": {
  "url": "https://your-api-endpoint.com",
  "credentialId": "cred_abc123" // Replace with your actual credential UUID
}

Go to the Vapi dashboard, create a credential, and copy its ID into your workflow as shown above.

But when i change everything, download it, manually delete this part, upload it again, then it works, but thats no solution. Also i cant seem to update any Structured Outputs. Is your system running can i change and save anything?
