    applicationInferenceProfile?: string

    Optional URL Encoded overide for URL model parameter in fetch. Necessary for invoking an Application Inference Profile. For example, "arn%3Aaws%3Abedrock%3Aus-east-1%3A1234567890%3Aapplication-inference-profile%2Fabcdefghi", will override this.model in final /invoke URL call. Must still provide model as normal modelId to benefit from all the metadata.
