Sounds silly but have you connected a 433mhz suitable antenna to the LoRa module?

The antenna issue is important, without the antenna you won't be able to transmit.
But "lora failed" is not an antenna problem, rather something wrong with the module most likely the connection.
Are you powering the Ra-02 module from the NodeMCU?
You should use an external power supply because the module can draw 200mA of power.
Check the docs: https://docs.ai-thinker.com/en/lora/man
Another thing: if things are not working you should simplify your setup and just connect the NodeMCU to the Ra-02 module remove the display and DHT sensor for now.
