helo, i'm running node.js v12.16.3 and node-red V1.0.4 on windows 10. I have installed the node red for OPCua with admin rights. If I use node-red on a normal user session, when I read an Item on a opcua server ( write is ok ), I obtain an internal error and in the command line I have :

error: ERROR!!! callback has thrown en error TypeError; cannot read property 'bold' of undefined  
at C:\..\AppData\Roaming\npm\node\_modules\node-red-contrib-opcua\opcua\102-opcuaclient.js:487:58  
...

Have you an idea what's happening ?  
thanks
