SQL10007N Message "0" could not be retrieved. Reason code: "6". in Azure Function

Is there anything special about using IBM.Data.DB2.Core with an Azure Function? The following code works fine outside of an azure function, but throws DB2Exception in a function.

Code:

var db2Connection = new DB2Connection(connectionString) {SystemNaming = true};

Exception:

IBM.Data.DB2.Core.DB2Exception (0x80004005): ERROR [] [IBM][CLI Driver] SQL10007N Message "0" could not be retrieved.  Reason code: "6".

It seems to be trying to read an XML configuration, possibly from the bin\Debug\netcoreapp3.1\clidriver\cfg path (which is deployed with the function).
