When can the "ArgumentNullException: ProviderName" error be encountered for the Database Activities?
Issue:
This error often occurs when the ProviderName parameter is not properly set or is missing.
The activity needs this parameter to identify the type of database it is connecting to.
The ProviderName specifies the ADO.NET provider to use for connecting to the database.
This parameter is critical because it determines how UiPath communicates with the database.
(e.g., SQL Server, Oracle, MySQL, etc.).
Resolution:
Make sure that the ProviderName is correctly specified either in the parameter or within the connection string.
When configuring the 'Connect' activity, ensure the ProviderName property is set to "System.Data.SqlClient" if it's SQL Server.
Replace "System.Data.SqlClient" with the appropriate provider name based on the database.
e.g., "System.Data.OracleClient" for Oracle).
When using a connection string to connect to the database, ensure that the connection string includes ProviderName=System.Data.SqlClient; (or the appropriate provider for the database).
