[oatpp::sqlite::Executor::getConnection()]: Error. Can't connect

I am building a project with the given CMakeLists.txt with conan:

cmake_minimum_required(VERSION 3.1)
set(PROJECT_NAME my-project)
project(${PROJECT_NAME})

set(CMAKE_CXX_STANDARD 14)

enable_testing()
add_test(e2e-tests ${PROJECT_NAME}-test)

Using this yields me a working executable on my machine running ubuntu 20.04. But when I move this executable to a LXD container running ubuntu 20.04, I get the following error:

ubuntu@container:~$ ./my-project-exe 
terminate called after throwing an instance of 'std::runtime_error'
  what():  [oatpp::sqlite::Executor::getConnection()]: Error. Can't connect.
Aborted (core dumped)

ubuntu@container:~$ sudo ./my-project-exe 
terminate called after throwing an instance of 'std::runtime_error'
  what():  [oatpp::sqlite::Executor::getConnection()]: Error. Can't connect.
Aborted (core dumped)

Looks like the database file db.sqlite fails to create. How can I eliminate this error?

Hey @ajinkyabawaskar ,

Looks like the database file db.sqlite fails to create. How can I eliminate this error?

Please make sure you have permissions to create file.

@lizemin5235 , you can use try - catch
