Problem to execute two Nodes "MS Authenticators"

Hello,
I have two Nodes “MS Authenticators”. one to read data from SharePoint, and other to share data to PowerBI, the problem that once i excite any one of them, the other one gives me this error:
Coding issue: Cannot invoke “String.isEmpty()” because the return value of “org.knime.core.node.defaulnodesttings.settingsModelString.getStringValue()” is null .
is there any recommendations?

Hello @RamyHussein,

and welcome to KNIME Community!

But you can only use (and actually need) one Authenticator node in a single workflow because you can create multiple output connections from one node.

For example:
MultipleConn

Or you have some other setup/use case for which you must have two Authenticator nodes?

Thank you @ipazin ,
in fact i would like to get data from SharePoint, and publish it to PowerBI.
is there any ides about the Nods needed?

Hello @RamyHussein,

your design seems fine. As said in my previous reply you can only use one Microsoft Authentication node if it has all the scopes necessary for both SharePoint Online List Reader and Send to Power BI node. From your original post I understood that having two nodes for authentication is giving you error. If that is the case then using only one should resolve your issue.
