OPC UA adapter unsupported protocol error
Hello everyone,
can the OPC UA adapter (in Streampipes 0.67.0) be used to read values from an OPC UA server that requires user credentials to log in? If I try to specify the OPC server URL in the sense of
opc.tcp://username:password@server:port
the following error is thrown:
org.apache.streampipes.connect.adapter.exception.AdapterException: Could not guess schema for opc node! UaException: status=Bad_InternalError, message=unsupported protocol: null
In the UI, I cannot see an alternative way to specify user credentials. Is it (yet) possible to use the OPC UA adapter in this setting?
Thank you very much for your help!
Best regards,
Adrian

Hi Tim,
thank you for the pull request, I merged it and closed the issue in jira.

Hi all,
I added the option to create an authenticated connection using the OPC-UA adapter and tested it with the milo demo server.
The changes are part of PR-35 (https://github.com/apache/incubator-streampipes-extensions/pull/35) in StreamPipes Extensions.
@Adrian, please let me know if it worked for you too or if you still face issues once the changes are included in the build of the 0.68-SNAPSHOT version.
Best,
Tim

Hi all,
indeed, the OPC-UA adapter currently does not support establishing a connection using credentials.
I have already done some experiments to add this feature to the OPC-UA adapter and think that this feature should be available in the near future.
Best regards,
Tim

Hi Adrian,
AFAIK this is not yet implemented. This is the part in the code where we define the opc ua server url in the constructor of a helper [1]. These information are injected by the adapter class [2].
I guess similarly to our MQTT protocol implementation we should add an alternative field as part of the model declaration in order to extract username/password if provided by the user (see declareModel method) [3].
Maybe @Tim or @Philipp know more about some of the details since they worked on the OPCUA adapter.
