> {color: red}Please, ANSWER this question AT{color} https://stackoverflow.com/questions/68064277/can-not-access-lazy-attribute-in-fiware-opc-ua-agent
> +Question:+
> Can not access Lazy attribute in FIWARE OPC-UA Agent
> +Description:+
> Context
> Used code base and tutorial: FIWARE IoT Agent for OPC-UA tutorial
> Target
> To access all available attributes both from IoT Agent and Orion Context Broker
> To modify attributes via commands sent to Orion Context Broker then passed down to IoT Agent
> Replicate steps
> Clone repo and start containers
> git clone "https://github.com/Engineering-Research-and-Development/iotagent-opcua"
> cd iotagent-opcua
> docker-compose up -d
