James Coulson updated NIFI-14626:
---------------------------------
Description:
When configuring the MongoDBControllerService, trying to validate or enable the
service results in a connection test failure with the error "username/password
can not be null". This happens when using the connection string that does not
contain any credentials (as the credentials are defined in the Database User
and Password Property) eg:
{code:java}
mongodb://server:27017/?tls=true&authMechanism=SCRAM-SHA-256 {code}
Adding the credentials to the connection URI but leaving them blank in the
controller properties also triggers this error.
A workaround found was to add the credentials in the MongoURI property eg:
{code:java}
mongodb://username:password@server:27017/?tls=true&authMechanism=SCRAM-SHA-256
{code}
while also specifying them in the properties of the controller.
