Description

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,
