Hey guys. I’ve been running into problems with

EmailTask

in

state_handlers

. I want to receive a email message that shows

task

and

new_state

when failures occur. My handler looks something like this:

def email_on_failure(task, old_state, new_state):
    if new_state.is_failed():
         task = EmailTask(
            subject="Prefect alert: {}".format(new_state),
            msg = "Task: {}; New State: {}".format(task, new_state),
            email_from='xxx',
            email_to='xxx',
            smtp_server='smtp.gmail.com',
            smtp_port=xxx,
            smtp_type='STARTTLS'
        ).run()

In tests, I can always receive the email with the correct subject, but the

task

and the

new_state

was always missing in the

msg

…Anyone has encountered similar problems?

hmmm, I wonder if this has to do with html interpreting the

<>

brackets on the state as something? Try using

html.escape

to fix this:

import html

def email_on_failure(task, old_state, new_state):
    if new_state.is_failed():
         task = EmailTask(
            subject="Prefect alert: {}".format(new_state),
            msg = html.escape("Task: {}; New State: {}".format(task, new_state)),
            email_from='xxx',
            email_to='xxx',
            smtp_server='<http://smtp.gmail.com|smtp.gmail.com>',
            smtp_port=xxx,
            smtp_type='STARTTLS'
        ).run()

@Jim Crist-Harif It worked perfectly, thank you!
