Trac Notification Error - Template error

[Iqbal Ahmad]

Hi,

 I am using the defalut template as mentioned in ticket_notify_email.txt and  also customization of email content.  My ticket_notify_email.txt looks like:

$ticket_body_hdr

--------------------------------------------------------------------------

# set sel = ('Reporter', 'Owner', 'Type', 'Status', 'Priority', 'Milestone',

             'Component', 'Severity', 'Resolution', 'Keywords')

# for a in ticket_props.replace('|', '\n').splitlines()[1:-1]|map('trim'):

#   set a = a.split(':', 1)|map('trim')|list

#   if len(a) > 1 and a[0] in sel:

${'%-*s  %s'|format(12, a[0] + ':', a[1])}

#   endif

# endfor

--------------------------------------------------------------------------

{% choose ticket.new %}\

{%   when True %}\

$ticket.description

{%   end %}\

{%   otherwise %}\

{%     if changes_body %}\

${_('Changes (by %(author)s):', author=change.author)}

$changes_body

{%     end %}\

{%     if changes_descr %}\

{%       if not changes_body and not change.comment and change.author %}\

${_('Description changed by %(author)s:', author=change.author)}

{%       end %}\

$changes_descr

--

{%     end %}\

{%     if change.comment %}\

${_('Comment:') if changes_body else _('Comment (by %(author)s):', author=change.author)}

$change.comment

{%     end %}\

{%   end %}\

{% end %}\

${'-- '}

${_('Ticket URL: <%(link)s>', link=ticket.link)}

$project.name <${project.url or abs_href()}>

$project.descr

And when I modify ticket I get the following error: 

2020-04-15 21:18:04,558 Trac[mail] DEBUG: EmailDistributor has found the following formats capable of handling 'email' of 'ticket': text/plain

The default template has been updated (1). You can start with that, and apply the changes for Outlook (2).
