I'm trying to build out a workflow I created three notes so far and every time I try to save it I keep getting an error. It's not allowing me to save. I've went over this many many times and everything is selected, including model type, but for some reason, it just won't save. Here is the error that I keep getting. What am I doing wrong? I cant figure out why it wont let me save it, Here is the error message: Save Failed Failed to save workflow: each value in nodes.model.provider must be one of the following values: openai, anthropic, google, custom-lIm.

The error means at least one of your workflow nodes has an invalid

model.provider

value. Make sure every node's provider is set to one of these exact values: -

openai

-

anthropic

-

google

-

custom-llm

(not "custom-lIm") Example node config:

json
{
  "type": "conversation",
  "model": {
    "provider": "openai",
    "model": "gpt-4.1-2025-04-14"
  }
}

Double-check for typos or incorrect casing in your workflow nodes and try saving again. [See API docs for details](https://docs.vapi.ai/api-reference/workflow/workflow-controller-create?explorer=true) Source: - [Vapi API Reference: Create Workflow](https://docs.vapi.ai/api-reference/workflow/workflow-controller-create?explorer=true)

All my nodes have models selected from the drop down menu so I am using whatever is available for me to use which in my case is OpenAi as the provider and the model is Chat 40 cluster.

Duplicate the workflow, then delete every node except for one and save. See if you still get the error. If you don't, add each node one by one saving on each node you add. Repeat the process until you have all your nodes back. If you want us to take a look at your workflow config, please use the API GET /workflow endpoint on your workflow id and send the response. -->
