HTTP error 400

[endiom]

"INCstring(215) "Webhook message delivery failed with error: Microsoft Teams endpoint returned HTTP error 400 with ContextId tcid=0,server=msgapi-production-wuk-azsc6-1-44,cv=Bsl8E+rFTkyPhteKHUmpOQ.0,MS-CV=Bsl8E+rFTkyPhteKHUmpOQ.0.."

loading data from json as $str to an ActionCard

"sections": [ { "activityTitle": "text", "facts": $str, "text": $text }

Once the records are too many the error occurred (screenshot of json), is there a maximum length for attribute "facts"? How to get rid of it?

HI @endiom Could you please provide JSON file. So that I can repro from my end and come back to you.

If I deleted some records, make it less it works.
