Error Calling SQLSetDescRec via PolyBase

When trying to query an external table created for a generic ODBC external data source, the following error can be observed:

Message 7320, level 16, state 110, line 87

Unable to execute query “Remote Query” against OLE DB provider “MSOLEDBSQL” on link server “(null)”. 105082; Generic ODBC error: OdbcBufferReader.ReadBuffer, error in OdbcReadBuffer: SqlState: IM001, NativeError: 0, ‘Error calling: SQLSetDescRec(this->GetHdesc(), (SQLSMALLINT)column->idxServerCol, (SQLSMALLINT)column->odbcReadType, 0, column->valueLength, (SQLSMALLINT)column->precision, (SQLSMALLINT)column->scale, (SQLPOINTER)(pBuffer + column->valueOffset), (SQLLEN *)indPtr, (SQLLEN *)indPtr), SQL return code: -1 | SQL Error Info: Error <1>: ErrorMsg: [Microsoft][ODBC Driver Manager] The driver does not support this function. | Error calling: pReadConn->ReadBuffer(pBuffer, bufferOffset, bufferLength, pBytesRead, pRowsRead) | state: FFFF, number: 239, active connections: 9’, Connection String: Dsn={DSN Name};Driver={Driver Name};uid=root;server=xxxxx;port=xxxx;database=xxxx.
