I am trying to access the azure variables in the Mule Flows as a property
I have added the variables in azure pipeline goals but those are not accessing. Couldn't find configuration property value for key ${test.username} from properties provider environment properties provider - within resolver Deployment properties trying to process key test.username
${test.username}like this it means this property is in your properties file. Check on which environment you deploy and then check the corresponding property file.If its missing you have to add a value in that property, for example:
test.username=test.
