Cannot add property heading_name, object is not extensible

[iptvcld]

I have the below entities:

• sensor.canadian_imperial_bank_of_commerce
• type: custom:entity-attributes-card entity: sensor.canadian_imperial_bank_of_commerce

  heading_name: Test

      filter:
        include:
          - sensor.canadian_imperial_bank_of_commerce.lastPriceUpdated
          - sensor.canadian_imperial_bank_of_commerce.change
          - sensor.canadian_imperial_bank_of_commerce.changePercent
          - sensor.canadian_imperial_bank_of_commerce.highestPrice
          - sensor.canadian_imperial_bank_of_commerce.lowestPrice

ERROR: Cannot add property heading_name, object is not extensible type: 'custom:entity-attributes-card' entity: sensor.canadian_imperial_bank_of_commerce filter: include:

This one is bothering my as well. I can see, the moment I but something under the include part this message appears.

Have been tinkering with it a bit and did not find any solution.

A simple workaround: Define 'heading_name' and 'heading_state' in your card definition. E.g.

entity: sun.sun
filter:
  include:
    - sun.sun.next_rising
    - sun.sun.next_setting
    - sun.sun.next_dawn
    - sun.sun.next_dusk
type: 'custom:entity-attributes-card'
heading_name: Name
heading_state: State

heading_name: ' ' heading_state: ' ' works a bit better..
