I see this issue in the st2sensorcontainer log.

Which sensors are you running there?

[LindsayHill]

Need some more info on what sensors/config you're running there. Can re-open if we have that info

Hi,

I am also getting same error:-

-: While trying to execute for following block of code in sensor:-
Following block of code iterates over all the unread emails in inbox and mark then as read
Code in Sensor

for item in account.inbox.filter(is_read=False):
item.is_read = True
item.save()
self._logger.debug(item.author.email_address)

This code is working as expected in Python But Throwing error mentioned above while executing it via sensor

@tonybaloney Did you find any resolution ?
@LindsayHill Please help

[LindsayHill]

Which sensor?

[guptasakshi01]

Sensor to monitor mailbox.That uses exhangelib module of python.

[LindsayHill]

Is this your own custom code? Please post a link to the code

[guptasakshi01]

Please find link for code.

https://github.com/guptasakshi01/St2/blob/master/monitor_mailbox.py

I am facing issue on line number 87. Where We are iterating over all the unread mails containing subject as Test
Whereas same block in working fine with python.
Please help

@guptasakshi01 It looks like some issue related to threading interaction with eventlet monkey patch.

I would try replacing:

eventlet.monkey_patch(
    os=True,
    select=True,
    socket=True,
    thread=True,
    time=True)

with

eventlet.monkey_patch(
    os=True,
    select=True,
    socket=True,
    thread=False,
    time=True)

In your sensor code.

And if that doesn't work, removing eventlet.monkey_patch line all together.

You should probably also look at the existing MS Exchange pack https://github.com/StackStorm-Exchange/stackstorm-msexchange/

I believe that has issues in some scenarios, but it would be better to start with that, and fix that, rather than write your own code. Better to leverage other's work, and share your improvements.

@LindsayHill We are not able to use senders email address in this given sensor, Is there any other way I can use the email address of sender as payload while dispatching trigger?

@Kami It didn't work Is there any other solution??

[LindsayHill]

It looks like it would be trivial to modify the existing sensor to also return the sender ID. e.g. probably change this line https://github.com/StackStorm-Exchange/stackstorm-msexchange/blob/master/sensors/item_sensor.py#L52 and the item_sensor.yaml.

Have you tried doing that, rather than writing a whole new sensor?

[guptasakshi01]

Hi @LindsayHill ,
I am receiving same error while using (existing module) item_sensor.py.

@guptasakshi01 Which StackStorm version are you using?

If you didn't upgrade yet, try upgrading to v2.7.2.

[guptasakshi01]

@Kami stackstorm version :- st2 2.7.1

[guptasakshi01]

@Kami Thanks for your help
It worked as expected with 2.7.2

[Kami]

Great - glad to hear that.

I will close that issue as resolved in v2.7.2.

[LindsayHill]

@guptasakshi01 now that we've fixed your problem, can you please submit a PR to the MSExchange pack to add the missing functionality that you needed? This will probably help someone else who needs it
