> Dear all,
> I use the Nifi from the docker container and need to pass the “Broker URI”
> value from environment variable. For this purpose, I initialize the docker
> container with “MQTT_URL=tcp://localhost:1883” environment variable and
> reference it from the process configuration.
> However, in this case, I receive “Broker URI is invalid because it is not
> valid URI syntax” notification. When I investigated more, I realized that
> “Expression language scope: Not Supported” for this property. I will truly
> appreciate, if you enable expression language for this property.
> (I think,
> ".expressionLanguageSupported(ExpressionLanguageScope.VARIABLE_REGISTRY)"
> statement need to be added to "PROP_BROKER_URI" property in
> org.apache.nifi.processors.mqtt.common.AbstractMQTTProcessor)
>
> Kind regard,
