Tip to myself: Use often the error output of a card

After changing a flow to make things less complex I had to change 4 of those type of cards.

This one was no longer passed on data for a few days.
In the flow I could not see anything what was wrong so I make first a timeline card and the end of the flow.
Later I get the feeling to take also the error output of the card for a message in the timeline to see the reason better.

After a few hours later I saw the error notification on my timeline and I was surprised.
Didn’t expect that message now. By testing the cart the error came again and not the yellow line.

By copy one of the other card and changed it carefully, the error was gone.
The yellow line game perfectly because the input was above 6 that time.

Next time I shall use that error output of a card sooner.
