## 2.83.3

**`(fix):`** Fix the generated root client passing a `grantType` argument to `OAuthTokenProvider`
when the token endpoint declares a required, non-literal `grant_type` property.
`OAuthTokenProvider` hardcodes `grant_type: "client_credentials"` and never took that
parameter, so the generated SDK failed to compile with
`'OAuthTokenProvider' does not contain a constructor that takes 4 arguments`.
