[C++][Restbed-server] Compilation error from missing function call parameter

[vbs96]

Description

The following compilation error occurs when I'm trying to compile a Restbed server from the given specification:

/api/FrameApi.cpp:70:91: error: expected primary-expression before ‘)’ token
    const bool includePictureBase64 = request->get_query_parameter("includePictureBase64", );

openapi-generator version

3.2.1(latest master branch with PR #752)

OpenAPI declaration file content or url

https://raw.githubusercontent.com/deepviss/deepviss-server-example/master/src/main/resources/deep-viss.json

Command line used for generation

Inside cloned repository, after mvn clean package command:

java -jar modules/openapi-generator-cli/target/openapi-generator-cli.jar generate/
        -i deep-viss.json /
        -g cpp-restbed-server /
        -o ../openapi-restbed-server

Steps to reproduce

Assuming Restbed is installed on local machine https://github.com/Corvusoft/restbed
I used the following cmake file:

cmake_minimum_required(VERSION 3.10)
project(restbed_ex)

set(CMAKE_CXX_STANDARD 11)

file(GLOB_RECURSE src_files mode/*.cpp api/*.cpp)

add_executable(restbed_ex main.cpp ${src_files})
target_include_directories(restbed_ex PRIVATE /restbed/include/)
target_include_directories(restbed_ex PRIVATE model/)
target_include_directories(restbed_ex PRIVATE api/)
target_link_libraries(restbed_ex restbed)

1)Go to output folder
2)Make a dummy main.cpp (touch main.cpp)
3)mkdir build && cd build
4)cmake ..
5)make
