terminate called after throwing an instance of 'nlohmann::detail::type_error'

[phadataretanu]

I am configuring libocpp for OCPP2.0.1 protocol.

I am able to build the code and generate executable of charge_point.

I am facing issues about 'nlohmann::detail::type_error' after ading config.json of OCPP2.0.1.

Executable getting crashed with following bug :
terminate called after throwing an instance of 'nlohmann::detail::type_error'
what(): [json.exception.type_error.305] cannot use operator[] with a string argument with array
Aborted

Can anyone help with the solution >

Hi @phadataretanu , I assume you are using the charge_point test executable. It is just an example that shows how the library can be used and integrated. This example is for OCPP1.6 only and does not work for OCPP2.0.1.

You need to integrate this library yourself with your charging station stack in order to use this library with OCPP2.0.1

Yes @Pietfried, I am using charge_point exe only. What steps do I need to follow if I want to use libocpp for ocpp2.0.1 implementation ?
