providers. .api_type is only supported for providers.openai

Error message

providers.<name>.api_type is only supported for providers.openai

What it means

In ProvidersConfig._validate_api_type_scope, api_type was set to something other than "auto" on a provider other than providers.openai (checked across all declared fields and custom extra providers). The explicit API surface override is only implemented for the OpenAI provider; the input at fault is the api_type on the named non-openai provider.

Solutions

  1. Move the provider settings under providers.openai if the api_type override is needed
  2. Reset api_type to "auto" (or remove it) for other providers
  3. Choose a built-in provider that natively matches the desired API surface
