IBM.Data.DB2.Core error in new DB2Connection(connectionString)

We have the IBM.Data.DB2.Core (3.1.0.300) nuget package installed in our .netstandard2.1 application library, to connect to an external DB2 instance on prem.
On running the following code from a .net core azure function v3 Windows 64bit (from a netcoreapp3.1 project)
var connectionString= "Server=DB2_IP:DB2_Port;Database=DB2_DBNAME;UID=DB2_UserId;PWD=DB2_Password;"
var connection = new DB2Connection(connectionString);
(note the values in the connection string are placeholders for anonymity)
We are receiving the following error
IBM.Data.DB2.Core.DB2Exception (0x80004005): ERROR [58005] [IBM][DB2.NET] SQL0902 An unexpected
exception has occurred in
Process: 21308 Thread 33 AppDomain: Name:Microsoft.Azure.WebJobs.Script.WebHost

at IBM.Data.DB2.Core.DB2Connection..ctor(String connectionString)
Does anyone have any idea where we're going wrong, or alternatively have a coherent end-to-end guide on the setup that may give me a clue.
All documentations I have found thus far has been rather sparse and a little inconsistent.

Unable to load shared library 'python37' or one of its dependencies

I am quite new to dotnet and Keras.NET, and I was trying to set it up on a goorm.io container. After installing the prerequisites (adding $HOME/.keras/keras.json for Tensorflow backend and pip install numpy), and then adding Keras.NET, I tried to run the XOR sample code, but ran into an error.
Unhandled exception. System.DllNotFoundException: Unable to load shared library 'python37' or one of its dependencies. In order to help diagnose loading problems, consider setting the LD_DEBUG environment variable: libpython37: cannot open shared object file: No such file or directory

I do not know how to share with the python37 directory. If someone could direct me in the right direction, it would be much appreciated. By the way, I am using Linux if that helps.
Thanks

TFS Git build breaks after updating build definition

Our TFS build has broken following updating the XAML build definition. Changes included modifying the template and a few parameters. The trace is below
TF215097: An error occurred while initializing a build for build definition [REDACTED]:

The build fails in the first few seconds as this is the process that is trying to retrieve the source. However, I cannot come to any conclusions as to why this error is happening. A Google search doesn't bring up anything useful.
TFS version 2013
Has anyone encountered this error and if so how did you fix it?
If I need to provide more information please ask.

When you modify the Build process template and therefore it’s no longer in sync with the build definition you may get TF215097 error.
#jessehouwing's suspicion makes sense. I can't find too many articles to elaborate this issue, but in this MSND documentation mentions, if you want to edit a custom template, You must use only Visual Studio 2013 to edit your build process templates of TFS 2013.

Semantic Logging Exception: Keywords values larger than 0x0000100000000000 are reserved for system use

I am using the Semantic Logging for my ASP.NET MVC app. https://github.com/mspnp/semantic-logging (SQL database) installed via nuget
Install-Package EnterpriseLibrary.SemanticLogging.Database
Here is the code that throws the exception.
var blockEventListener = new ObservableEventListener();
blockEventListener.EnableEvents(SemanticLoggingEventSource.Log, EventLevel.LogAlways, Keywords.All);
In my development platform using IIS Express, I don't have any exception but when I uploaded it to IIS 8.0 I got the following exception.
