How resolve this error Unexpected keyword or identifier in my code

I have a class that returns the data in a specific type CreateTenantInput

export class requestDto {
        @ApiProperty()
    
        readonly name: string;
        readonly tenant: string;
        readonly isActive: number;
    
        public function toInput(): CreateTenantInput {
            return new CreateTenantInput(this.name, this.tenant)
        }
    }

to use in a function that requires this type CreateTenantInput within the controller

@Post('/create')
async createTenant(
    @Body() request: requestDto)
{
     //alternative solution for the Dtio
    //const input:CreateTenantInput = new CreateTenantInput(request.name, request.tenant)
    return await (await new CreateTenantUseCase(request.toInput(), this.tenantRepository).handler(request)).result
}
