Not able to deploy after upgrade - Failed to connect (Azure Managed Instance) - Method Not found Exception


We have upgraded our TXT environment from 20.10.14 to 20.10.43 last week.

Install and repository/existing projects upgrade went well.

We can save the project. The new scheduler service runs correctly. Execute action is ok. 

However, we encounter an exception during table deployment task (BU/STAGE or DWH table):

Failed to connect to server XXX (Azure Managed Instance)
Method not found: 'System.Net.Http.Headers.HttpResponseHeaders Microsoft.Identity.Client.MsalServiceException.get_Headers()'.


The connection settings (Repository/STAGE/DWH) seem correct (positive test connection): same Azure Managed Instance.

We have checked the .NET framework version - it seems recent 4.8.03761

Thanks for your help.


Best regards

Hi @matthieu.carrat 

We will try to figure out what is going on.

Hi Thomas,

Thank you for your message. 


Indeed the error is on all the tables (stage and dwh). The databases are specifically on an Azure Manage Instance (same instance for all db including repository).

It is strange, it seems a problem with the connection settings but we don’t find a missing param. We don’t know if it is linked to the MethodNotFound exception or if this last one is just a consequence of the connection problem.

Hi @matthieu.carrat I have created a support ticket for this, let’s keep the communication in the support ticket

Any outcome on this connection issue?
We're encountering the same (upgraded from 20.10.26 to 20.10.43).

Hi @EelcoH 

We have a workaround, but not a release with a fix for this currently. I will send the method to you. A fix is currently being tested and will be released.
