MashupException.Error: The value is not updatable.

[m_cherriman]

I have a Dataflow in Fabric that connects to an on premise SQL Server and last week it was working and this week I am getting this error: Error Code: 999999, Error Details: Couldn't refresh the entity because of an issue with the mashup document MashupException.Error: The value is not updatable.

I got this error yesterday morning and had the data gateway updated yesterday afternoon in case this was the issue, but I still get the error.  The previous version of the gateway was only installed 2 weeks ago.  The current version of the gateway is 3000.198.9.

When I view the output in Dataflow it looks ok and is able to refresh.  Also there are no errors in the data.

Hi @Anonymous , I'm getting the same Error Code: 999999, Error Details: Couldn't refresh the entity because of an issue with the mashup document MashupException.Error: The value is not updatable.
as @knaidoo13 , yesterday we just updated our OnPremise DataGateway to the latest version 3000.182.4

PS : The Fabric documentation here explicitely talks about similar error and mention the upgrade to the latest OnPrem Gateway Version

Hi @Anonymous we didn't get any feedback from you on that matter so I created the support case 2311230050001043 ; please let me know if in the meantime you got any insight how to fix this issue so I can close my case. Thanks

it's seems that upgrading to version 3000.198.17 (November) fixed the issue

Hello @GuillaumeBer ,

Apologies for the delay in reply from our side. Yes, you are correct.
I also checked again with internal team, latest release on On-Prem Data Gateway (version 3000.198.17 ) - resolves the issue.

Download On-premises data gateway from Official Microsoft Download Center
