MODEL_NOT_FOUND
Currently only used in `langchainjs` (JavaScript/TypeScript).
The model name you have specified is not acknowledged by your provider.
Troubleshooting
To resolve this error:
- Verify the model identifier: Double check the model string you are passing in. Ensure the spelling and format are correct
- Check proxy/wrapper configurations: If you are using a proxy or other alternative host with a model wrapper, confirm that the permitted model names are not restricted or altered
The error typically stems from either a typo in the model name string itself or restrictions imposed by a proxy service or model wrapper between your code and the provider's API.
