Card button inexplicably stopped working

[Leslie Rieger]

Hi - I hope someone can help.

I have a card button that creates a daily to-do list for me by pulling together all the cards with a due date of today into linked items in a check-list.  The title for this to-do list card is generated as "To Do List {date~ M/D/YYYY}.  (This button still works perfectly, and I think the title is the only important piece for my question, but if you need to know more specifics about the list creation button, I can provide those details as well).

Because I occasionally forget to add a card, change a due date, or someone asks me for something during the day that needs to be added to that day's list, I also created a button that adds the open card to the current day's To Do list card's checklist as a linked item.

The following screenshot shows the actions for that button.

At 9:05 AM on January 14th, this button worked.  At 9:50 AM on the same day, I tried to use the button to add another card as a linked item on my To Do list card, and I got the error "I couldn't find a card named "To Do List 1/14/2022"."  I made no changes to either button between the time it worked and the time it didn't.

I tried the button again this morning, and got the same error (except it was "To Do List 1/18/2022"), so it doesn't seem to be just a random one-time glitch.

Does anyone see something I missed that might explain why this no longer works?  Or have any other ideas I could try?

Thanks!

Hey @Leslie Rieger - I can reproduce the issue you're describing, and I'm puzzled as to what's going on. The team's looking into it. I can get it to work without the date variable, so likely some bug crept in that's affecting this.

I'll post an update here once we've figured this out & sent a fix out.

Thank you!  At least now I know I'm not crazy. :)

Update

@Leslie Rieger I think we've figured this one out (and it's not a bug!).

Your button command's date variable includes an extra space, which seems to be trimmed in a bunch of places, like on the front of Trello card, so it's really hard to spot.

I've managed to get your example working, by changing:

To Do List {date~ M/D/YYYY}

to

To Do List {date~M/D/YYYY}

Note the removed space between "~" and "M".

Could you give that a shot and let me know if that fixes the issue for you too?

[Leslie Rieger]

That worked! Thank you so much!

this issue is back.  i am trying to add a card like i normally do, but when clicking the button, it disappears instead of allowing me to type out new card etc....hard page refresh brings the button back, but when clicking again, simply does the same cycle of making the button disappear.
