[BUG][TypeScript Angular] delete operation is broken

Created by: whydoievenneedthis

Description

The delete operations are broken. POST, PATCH and PUT supports a body as the second parameter of the call, with the options being at the third position. DELETE, however, requires the body to be put into the second option parameter.

Generated typescript code

        return this.httpClient.delete<any>(`${this.configuration.basePath}/thingy`,
          null,
            {
                context: localVarHttpContext,
                responseType: <any>responseType_,
                withCredentials: this.configuration.withCredentials,
                headers: localVarHeaders,
                observe: observe,
                reportProgress: reportProgress
            }
        );

Expected typescript code

        return this.httpClient.delete<any>(`${this.configuration.basePath}/thingy`,
            {
                context: localVarHttpContext,
                responseType: <any>responseType_,
                withCredentials: this.configuration.withCredentials,
                headers: localVarHeaders,
                observe: observe,
                reportProgress: reportProgress,
                body: null
            }
        );
