[jira] [Commented] (AIRFLOW-1099) Error "TypeError: Expected bytes, got newbytes" while using MS SQL as metadata database

["Marcelo G. Almiron (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/AIRFLOW-1099?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15966051#comment-15966051 ] 

Marcelo G. Almiron commented on AIRFLOW-1099:
---------------------------------------------

Looks like this is an issue only on Python 2.7 and it can be solved with {{future.utils.native}} function. In this case, I changed the {{Log.__init__}} function on {{models.py}} to apply {{native}} function on {{extra}} field.

> When accessing any DAG view from the initial page after log in, I get the error "TypeError: Expected bytes, got newbytes". This error occurs only while using MS SQL as metadata database (I tested with Postgres and works perfectly).
> Traceback is in attachment.
