MICROSOFT SQL SERVER CONNECTOR - Error in autentication

[albertoruggeri1]

Hello,
i’m new in Knime world, i would like to find a solution to this error:
WARN Microsoft SQL Server Connector 4:16 Errors loading flow variables into node : Coding issue: No enum constant org.knime.core.node.defaultnodesettings.SettingsModelAuthentication.AuthenticationType.C:\Users\ALBERTO.RUGGERI1\OneDrive - Gruppo HERA\Desktop\KNIME

I had a successfully authentication in the node before, i follow the instruction of the node about the installation of the KNIME Microsoft JDBC Driver For SQL Server.

If someone can give some suggestions or solutions, i would appreciate.

Many thanks,
Alberto

Hi,
Welcome to the KNIME Forum. It seems like you accidentally set one of the settings of the MS SQL Server Connector to be controlled by the flow variable “knime.workspace”.
From the message I assume it is the authentication → selectedType setting like you see in my screenshot. Please remove the flow variable selection here and instead select the blank value. That should fix your problem.
Kind regards,
Alexander
