Attempt to set variable to body of email fails with core dump

[scstraus]

Hi, when I try to set one of the variable attributes to the value of the body of an email from IMAP email sensor, I get the following (traceback at the bottom)

Here's another one, I tried to take out the body but it still failed:

        }

So, I've changed the configuration a bit which worked to make the template for the main value of the sensor work when I take out the attributes like this:

- id: posta_state_change
  alias: 'Posta state change'
  hide_entity: true
  initial_state: 'true'
  trigger:
    platform: state
    entity_id: sensor.cp_packages_coming_today
  condition:
    condition: state
    entity_id: 'sensor.cp_packages_coming_today'
    state: 'delivery'
  action:
    service: variable.set_variable
    data:
      variable: posta_variable
    data_template:
      value: >
          {{ states('sensor.cp_packages_coming_today')}}

But when I put the attributes back in like this:

- id: posta_state_change
  alias: 'Posta state change'
  hide_entity: true
  initial_state: 'true'
  trigger:
    platform: state
    entity_id: sensor.cp_packages_coming_today
  condition:
    condition: state
    entity_id: 'sensor.cp_packages_coming_today'
    state: 'delivery'
  action:
    service: variable.set_variable
    data:
      variable: posta_variable
      attributes_template: >
        {
          "from": "{{ state_attr('sensor.cp_packages_coming_today', 'from') }}",
          "date": "{{ state_attr('sensor.cp_packages_coming_today', 'date') }}",
          "subject": "{{ state_attr('sensor.cp_packages_coming_today', 'subject') }}",
          "body": "{{ state_attr('sensor.cp_packages_coming_today', 'body') }}"
        }
    data_template:
      value: >
          {{ states('sensor.cp_packages_coming_today')}}

I get this again:

2019-05-15 23:47:16 ERROR (MainThread) [homeassistant.core] Error doing job: Task exception was never retrieved

  File "/config/custom_components/variable/__init__.py", line 179, in async_set_variable

Okay, so the issue is with the size of the email body.. I was able to make it work with the below syntax, but as soon as I add the body on, it crashes just like above.

- id: posta_state_change
  alias: 'Posta state change'
  hide_entity: true
  initial_state: 'true'
  trigger:
    platform: state
    entity_id: sensor.cp_packages_coming_today
  condition:
    condition: state
    entity_id: 'sensor.cp_packages_coming_today'
    state: 'Delivery'
  action:
    service: variable.set_variable
    data:
      variable: posta_variable
      attributes_template: >
        {
          "from": "{{ state_attr('sensor.cp_packages_coming_today', 'from') }}",
          "date": "{{ state_attr('sensor.cp_packages_coming_today', 'date') }}",
          "subject": "{{ state_attr('sensor.cp_packages_coming_today', 'subject') }}"
        }
    data_template:
      value: >
          {{ states('sensor.cp_packages_coming_today')}}

Also I found a related SQL error.. sensor.dpd_packages_coming_today is the exact same sensor, just with different email content for a different shipping provider.

Error executing query: (MySQLdb._exceptions.DataError) (1406, "Data too long for column 'event_data' at row 1") [SQL: 'INSERT INTO events (event_type, event_data, origin, time_fired, created, context_id, context_user_id) VALUES (%s, %s, %s, %s, %s, %s, %s)'] [parameters: ('state_changed', '{"entity_id": "sensor.dpd_packages_coming_today", "old_state": {"entity_id": "sensor.dpd_packages_coming_today", "state": "Delivery", "attributes": { ...
