Slack: /trello failed with the error "invalid_blocks"

I've been using the Slack Power-up and Trello App for Slack in the same configuration with boards and channels for over a year.  On or around Dec. 28, I started getting an error -- /trello failed with the error "invalid_blocks" -- when trying to access some cards.

 

I receive notifications for cards created in a Slack Channel.  I then copy the link for the card and paste it into a new Slack message.  Prior to Dec. 28, the Trello App would retrieve card details.  Pasting in the link now results in no action at all.

 

I then attempt to use the /trello command, using the /trello [url] format.

 

Often this works. but sometimes I get the "invalid_blocks" error message I mentioned above.  I cannot narrow it down to when it will occur and when it won't.   I may have two notifications for cards created in the same list on the same board and the /trello command will return details of one card but give me the error message on another. 

 

Any ideas?  Thanks.
