json extension - fatal error during loading about duckdb

[lkordos]

Example:

#include "duckdb.hpp"
int main(int argc, char* argv[])
{
	auto db = std::make_unique< duckdb::DuckDB >(nullptr, nullptr);
	auto con = std::make_unique< duckdb::Connection >(*db);
	auto res1 = con->Query("LOAD json;");

	return 0;
}

Can you also share how to you invoke the compiler / variable passed to cmake or compiler?

[lkordos]

It is a console application (name.exe), compiled with MS VS 2022, 64bit app, default compiler settings used by VS.

if it helps, during the debugging I can see from the "con" that the parquet extension is loaded (by default) successfully.

I run the same code with the newest duckdb, version 0.10.2, and the error is more specific now:

Initialization function "json_init" from file "C:...duckdb\extensions\40e2ff4837\windows_amd64\json.duckdb_extension" threw an exception: "Missing DB manager"
