Unable to link Dataverse and SQL Server tables within Dataflows

Hello!

 

I am trying to link a Dataverse table to a SQL Server table in a Dataflow Mashup. 

 

Dataflows which contain only Dataverse tables work fine. Dataflows which contain only SQL Server tables work fine. So I am confident there isn't an issue with our Data Gateway, or permissions, etc. 

 

However, if I try to connect Dataverse as a data source to a Dataflow which already contains SQL Server tables, I receive the following error:

An exception occurred: 2 arguments were passed to a function which expects 1. (Session ID: d6cf1fe5-5338-4801-b421-8d63232da0a9, Region: uk)

 

If I do it the other way round (i.e. add SQL Server tables to a Dataflow which previously only included Dataverse tables), tables from both data sources are listed in the Queries panel on the left. However,  as soon as I try to link them, I receive the following error: 

"2 arguments were passed to a function which expects 1."

 

Has anyone come across this before? Or have any suggestions? 

 

Best regards, 

Ryan

Thank you Stephen. 

Upgrading the Gateway to the latest version (3000.122.8 - April 2022) appears to have done the trick.

Hi @ryan_L,

 

Please upgrade the gateway to the latest version and try connecting again.
