Juju charm: action failed: (ImportError: No module named 'charms.reactive')

As a newbie to juju framework, I'm invistigating simple machine deployment with the aim of executing simple action on it.

So, I've created a charm bundle, built it and deployed it successfully using juju. The bundle contains an action called "touch" that takes a string (i.e.: filename) as an input and create a file with that name on the machine.

After the machine becomes "active" and when I list actions in the deployed machine using:

juju actions charmLayer

I get my action listed alongside its description.

Now, when executing the actions "touch" using:

juju run-action charmLayer/0 touch filename="/home/ubuntu/manual.txt"

I get the following message:

Action queued with id: d6b39965-9a2c-41c6-8db7-b4060e587033

Then, when I check the action-status:

juju show-action-status d6b39965-9a2c-41c6-8db7-b4060e587033

I get the following:

actions:

action: touch

completed at: "2019-05-03 11:56:51"

id: d6b39965-9a2c-41c6-8db7-b4060e587033

status: failed

unit:

charmLayer/0

Then when I check the action-output:

juju show-action-output d6b39965-9a2c-41c6-8db7-b4060e587033

I get the following:

message: exit status 1

status: failed

timing:

completed: 2019-05-03 11:56:51 +0000 UTC

enqueued: 2019-05-03 11:56:48 +0000 UTC

started: 2019-05-03 11:56:51 +0000 UTC

when checking logs using :

juju debug-log

I see the following output:

unit-charmLayer-0: 13:23:14 DEBUG unit.charmLayer/0.touch Traceback (most recent call last):

unit-charmLayer-0: 13:23:14 DEBUG unit.charmLayer/0.touch File "/var/lib/juju/agents/unit-charmLayer-0/charm/actions/touch", line 6, in

unit-charmLayer-0: 13:23:14 DEBUG unit.charmLayer/0.touch from charms.reactive import main, set_flag

unit-charmLayer-0: 13:23:14 DEBUG unit.charmLayer/0.touch ImportError: No module named 'charms.reactive'

My question why am I getting this ImportError for the charms.reactive ?

Can you post your code? We might be able to help if we can see how you've composed your charm. (this should be a comment, not an answer. I don't have the rep).

In answer, are you importing charms.reactive? If you're writing a reactive charm it should have been included for you already if you did charm init. Otherwise you might need to add import charms.reactive at the top of your Python script.
