Blockly - Average calculation no longer works in OH4

Hi!

I just noticed that with the Blockly editor, averaging values no longer works.
There is a JavaScript error in the log.

The goal is to get the average of an outlet for the last 5 minutes, and then perform other actions.
The script:

The error also occurs when I add the item directly at “of item” and do not go via a variable.

The error:

Did I make a mistake or is something currently broken in openHAB4?

Your variable doesn’t hold the item but the numeric state of the item and you then use the numeric state of the item to retrieve the average, which is wrong. Blockly cannot detect your mistake because it cannot check the type of a variable.

To fix this, use getItem(item Zigbee…) in the “get the state average” block.
