[Bug]: mushroom.js:298 Uncaught (in promise) TypeError: Cannot read properties of undefined (reading 'config')

[pganansia]

Requirements

• I checked the troubleshooting section in the README to verify that I have the latest Mushroom version.
• I did a search to see if there is a similar issue or if a pull request is open.
• I have read the state of card mod support (in pin issues) and understand card mod support is not provided in this repository.

Current Behavior

Since few I get this error message using mushroom-template-card
mushroom.js:298 Uncaught (in promise) TypeError: Cannot read properties of undefined (reading 'config')

In mushroom.js, the error is on

The other mushroom cards are not producing error.
Am I doing something wrong ?

Rgds.
