What is the correct configuration for Monolog / Swiftmailer Html Formatter in Symonfy2?

I'm having trouble setting up Monolog to use Swiftmailer and the Html formatter. I have multiple monolog handlers and swiftmail mailers which might be the issue. Here's my config.yml Monolog section: ``` services: monolog.formatter.html: class: Monolog\Formatter\HtmlFormatter monolog: channels: ["orders", "support"] handlers: # Called orders: type: stream path: "%kernel.logs_dir%/%kernel.environment%_orders.log" level: info channels: orders # Called support: type: fingers_crossed action_level: critical handler: support_grouped channels: support # Not called, referenced in a handler [support] support_grouped: type: group members: [support_log, environment_log, support_buffered] # Not called, referenced in a group handler [grouped_support] support_buffered: type: buffer handler: support_buffered_grouped # Not called, referenced in a handler [support_buffered] support_buffered_grouped: type: group members: [hipchat, webmaster_email, support_email] # Not called, referenced in a group handler [support_buffered_grouped] support_email: type: swift_mailer mailer: swiftmailer.mailer.errors from_email: %webmaster_email_address% to_email: %support_email_address% subject: '[Costimator] Support: An Error Occurred!' level: debug content_type: text/html formatter: monolog.formatter.html # Called webmaster: type: fingers_crossed action_level: critical handler: webmaster_grouped # Not called, referenced in a handler [webmaster] webmaster_grouped: type: group members: [environment_log, webmaster_buffered] # Not called, referenced in a handler [webmaster_grouped] webmaster_buffered: type: buffer handler: webmaster_buffered_grouped # Not called, referenced in a handler [webmaster_buffered_grouped] webmaster_buffered_grouped: type: group members: [hipchat, webmaster_email] # Not called, referenced in a group handler [webmaster_buffered_grouped, support_buffered_grouped] webmaster_email: type: swift_mailer mailer: swiftmailer.mailer.errors content_type: text/html from_email: %webmaster_email_address% to_email: %webmaster_email_address% subject: '[Costimator] An Error Occurred!' level: debug formatter: monolog.formatter.html # Not called, referenced in a group handler [support_grouped, webmaster_grouped] environment_log: type: stream path: "%kernel.logs_dir%/%kernel.environment%.log" level: debug # Not called, referenced in a group handler [support_grouped, webmaster_grouped] support_log: type: stream path: "%kernel.logs_dir%/%kernel.environment%.support_log" level: debug # Not called, referenced in a group handler [webmaster_buffered_grouped, support_buffered_grouped] hipchat: type: hipchat notify: true token: xxx room: xxx level: critical ``` Swiftmailer section: ``` # Swiftmailer Configuration swiftmailer: default_mailer: %mailer_default_config% mailers: default: delivery_address: "%mailer_delivery_address%" transport: "%mailer_transport%" host: "%mailer_host%" username: "%mailer_user%" password: "%mailer_password%" spool: type: "%mailer_spool_type%" path: "%kernel.root_dir%/spool" errors: delivery_address: "%mailer_errors_delivery_address%" transport: "%mailer_errors_transport%" host: "%mailer_errors_host%" username: "%mailer_errors_user%" password: "%mailer_errors_password%" spool: type: "%mailer_errors_spool_type%" path: "%kernel.root_dir%/spool" ``` Errors are being sent as text/html but without the table formatting. Any ideas? // Ping @seldaek Edit Formatters seem to be set on the handlers:
