What’s happening?
Experiencing a forbidden error when using an adaptive card with input text elements that exceed two lines, despite enabling the 'isMultiline' property and attempting to set a maximum character limit.
 

Reason:
The forbidden exception is not caused by sending an adaptive card itself, but rather by the bot calling a flow.
 

Resolution:

  • Ensure that the 'isMultiline' property is enabled for the input text elements in the adaptive card.
  • Attempt to set a maximum character limit for the input text elements.
  • Capture the network trace while reproducing the error and attach that file for further analysis.
  • Provide the Bot ID, conversation ID, and tenant ID to support for troubleshooting.
